Superstation

==United States==
===Early television superstations===
In the early days of television broadcasting, most large [[media market]]s – primarily those ranked among the top 20 in [[Nielsen Audio|Arbitron]] and [[Nielsen Media Research|Nielsen]] estimates – had, by standards of the period, a sizeable number of television stations (sometimes as many as eight or nine in operation). Generally, these markets had three [[Very high frequency|VHF]] stations that operated as [[network affiliates|affiliates]] of the then dominant television networks – [[NBC]], ABC, and [[CBS]]; one or more [[public television]] stations – which usually were [[Network affiliate#Member stations|member stations]] of [[National Educational Television]] (NET) and its later successor, the Public Broadcasting Service ([[PBS]]); one or more [[Ultra high frequency|UHF]] stations; and in the largest markets (such as New York City, Los Angeles and Chicago), at least one VHF station without a network affiliation. These [[Independent station (North America)|independent stations]] generally relied on syndicated reruns of current or defunct network shows, classic theatrical feature films and some variety of local programming – such as news programs (ranging from as limited as hourly news updates to long-form newscasts, usually airing in prime time and, in some cases, at midday), children's programming or sporting events – to fill their broadcast schedules. Because of the available population reach of the region, most mid-sized and smaller media markets often had only the basic three [[network affiliate|network-affiliated]] stations (either in the form of three standalone affiliates or a primary-secondary structure in which one or two stations carried programs selected among the schedules of two or all three major networks), with imported network affiliates often serving as default outlets where one or more networks were not available locally.

Early community antenna television (CATV) systems were restricted from retransmitting distant signals to communities no more than approximately {{convert|100|mi|km}} from the closest signal, which was a detriment to many small communities, especially sparsely populated areas of the Western United States, that were too distant from any receivable signal.<ref name="mbc-distantsignals">{{cite web|title=Distant Signals|url=http://www.museum.tv/eotv/distantsigna.htm|website=Museum of Broadcast Communications|access-date=April 30, 2019|url-status=dead|archive-url=https://web.archive.org/web/20140203221219/http://www.museum.tv/eotv/distantsigna.htm|archive-date=February 3, 2014}}</ref> As CATV system capacity increased from three channels to five during the early 1950s, several communities in the Western U.S. began incorporating CATV systems using [[microwave transmission|microwave relay systems]] that made it possible to retransmit broadcast signals over great distances. In September 1956, Columbia Television Co. in [[Pendleton, Oregon]] began using a microwave relay unit operated by Inland Microwave Co. to import three [[Spokane, Washington]] television stations, ABC affiliate [[KREM-TV]] (channel 2, now a CBS affiliate), CBS affiliate [[KXLY-TV]] (channel 4, now an ABC affiliate) and NBC affiliate [[KHQ-TV]] (channel 6), to its subscribers. Building on this, other [[cable television|cable and CATV systems]] in smaller municipalities and rural areas sought a foothold by "importing" broadcast television signals from larger nearby or distant cities for their customers, extending their reach beyond their normal coverage area (in the case of network-affiliated stations, this was to improve reception into areas that could not adequately receive the station's signal, whether within or at the edge of the contour, even with an outdoor antenna). Anxious for more viewers, the stations assisted by relaying their signals by wire or microwave transmission.

Within a few years, many other microwave-capable CATV system operators began to import out-of-market television signals based on program offerings they thought would appeal to their subscribers. Except for areas that were far enough out of a signal's reach to make this an unviable option, these systems selected major-market independent stations (often located anywhere between {{convert|60|and|200|mi|km|disp=sqbr}} away from the relay towers) that aired popular feature films and local sports events. In 1962, [[Oneonta, New York]]-based Eastern Microwave Inc. (EMI) – a company that was developed after a technician employed with the parent CATV system observed the operations of [[Montana]]-based microwave-to-CATV firm Western Microwave – was founded to relay the signals of WPIX, [[WNYW|WNEW-TV]] and [[WOR-TV]] (channel 9, now [[MyNetworkTV]] owned-and-operated station [[WWOR-TV]] and licensed to [[Secaucus, New Jersey]]) to Oneonta Video and other CATV systems in surrounding areas. Eastern Microwave began distributing WOR-TV and either WPIX or WNEW (depending on the system) in March 1965 to three Upstate New York cable systems (Valley Cable Vision in [[Canajoharie, New York|Canajoharie]], Carthage Video Division in [[Carthage, New York|Carthage]] and Cortland Video in [[Cortland, New York|Carthage]]).<ref>{{cite magazine|title=For the Record|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=100|date=February 15, 1965}}</ref> Other microwave firms were also developed to relay independent television stations to cable systems, including H&B Microwave (a subsidiary of H&B Communications Corp., a major provider of CATV service and microwave relays throughout the U.S.), which began retransmitting the signal of [[WGN-TV]] (channel 9) in Chicago to subscribers of the Dubuque TV-FM Cable Company in [[Dubuque, Iowa]]; WGN's signal soon began to be imported via microwave to other CATV systems throughout the [[Midwestern United States|Midwest]].

Because of changes to cable television regulations in the 1960s and 1970s, carriage of out-of-market independent stations increased significantly, allowing for the development of the first true "regional superstations." By way of the microwave connections, [[Ted Turner]] began allowing the signal of [[Atlanta|Atlanta, Georgia]] independent station WTCG (channel 17, later renamed WTBS and now [[WPCH-TV]]) – which he purchased from station founder and fellow Atlanta-based entrepreneur Jack Rice Jr. in December 1969 in a $3-million all-stock transaction – to be distributed into other parts of the Southeastern United States (including [[Alabama]], [[Tennessee]] and [[South Carolina]]). Two major independent station operators began extending coverage of their stations throughout their respective home states and even surrounding states. [[Gaylord Entertainment Company#Television stations formerly owned by Gaylord|Gaylord Broadcasting]] began allowing its independents—[[WUAB]] (channel 43, now a CW affiliate) in [[Lorain, Ohio|Lorain]]–[[Cleveland]], [[WVTV]] (channel 18, now a CW affiliate) in [[Milwaukee, Wisconsin|Milwaukee]], [[KSTW]] (channel 11, now a CW owned-and-operated station) in [[Tacoma, Washington|Tacoma]]–[[Seattle]], [[KTVT]] (channel 11, now a CBS owned-and-operated station) in [[Fort Worth, Texas|Fort Worth]]–[[Dallas]] and KHTV (channel 39, now CW affiliate [[KIAH]]) in [[Houston]]—to be distributed to cable systems in their respective regions, as did the [[Christian Broadcasting Network]]'s Continental Broadcasting Network unit for two of its religious-secular hybrid independents, WYAH-TV (channel 27, now CW affiliate [[WGNT]]) in [[Virginia Beach, Virginia|Virginia Beach]] and [[KXTX-TV]] (channel 39, now a [[Telemundo]] owned-and-operated station) in Dallas–Fort Worth.

===WTCG: The first national superstation===
In December 1975, Ted Turner announced plans to redistribute Atlanta's WTCG via satellite to cable and [[C band (IEEE)|C-band satellite]] services throughout the United States, beyond the 460,000 households in middle and southern Georgia and surrounding Deep South states that had been receiving its signal via microwave since the early 1970s. (Jack Matranga, then the president of [[KTXL]] [channel 40, now a Fox affiliate] also unveiled similar plans for his [[Sacramento, California]] independent, which were never formulated to fruition.) Turner conceptualized the idea upon hearing of [[pay television|premium cable service]] Home Box Office ([[HBO]])'s groundbreaking innovation to retransmit its programming nationwide using [[communications satellite]]s beginning with its September 30, 1975, telecast of the "[[Thrilla in Manila]]" boxing match.<ref>{{cite magazine|title=Broadcasters eye satellite feed to distant cables|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=47|date=December 1, 1975}}</ref><ref>{{cite web|title=Communications History – Home Box Office|url=http://www.fcc.gov/omd/history/tv/1960-1989.html|author=FCC Internet Services Staff|publisher=Federal Communications Commission|access-date=October 5, 2012|archive-url=https://web.archive.org/web/20070202210308/http://www.fcc.gov/omd/history/tv/1960-1989.html|archive-date=February 2, 2007}}</ref> With a more cost-effective and expeditious distribution method in place than would be capable through setting up microwave and coaxial telephone relay systems across the entire country, Turner got his idea off the ground by founding [[Satellite Syndicated Systems|Southern Satellite Systems]] (SSS) – a common carrier uplink provider based in [[Tulsa, Oklahoma]] – to serve as the station's satellite redistributor, and subsequently purchased an earth-to-satellite transmitting station to be set up outside of WTCG's Peachtree Street studios in Atlanta. To get around FCC rules in effect at the time that prohibited a common carrier from having involvement in program origination, Turner decided to sell SSS to former [[Western Union]] vice president of marketing Edward L. Taylor for $1 and sold the transmitting station to [[SES Americom|RCA American Communications]]. Upon the sale's consummation in March 1976, Turner reached an agreement with Taylor to have the firm uplink the WTCG signal to the [[Satcom (satellite)|Satcom 1]] satellite.<ref>{{cite magazine|title=Turner cranks up for satellite feed|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=118|date=March 22, 1976}}</ref><ref name="wapo-turner">{{cite news|title=Super Station's Super Man|url=https://www.washingtonpost.com/archive/lifestyle/1979/02/11/super-stations-super-man/416b0082-6659-45ad-a1af-5bc77e84895e/|author=Christian Williams|newspaper=[[The Washington Post]]|date=February 11, 1979|access-date=April 29, 2019}}</ref>

WTCG became America's first nationally distributed superstation on December 17, 1976, when its signal began to be relayed to four cable systems in the [[Midwestern United States|Midwestern]] and Southeastern United States. At 1:00&nbsp;pm. ET (12:00&nbsp;pm. CT) that day, subscribers of Multi-Vue TV in [[Grand Island, Nebraska]], Hampton Roads Cablevision in [[Newport News, Virginia]], Troy Cablevision in [[Troy, Alabama]] and Newton Cable TV in [[Newton, Kansas]] began receiving WTCG's presentation of the 1948 [[Dana Andrews]]-[[Cesar Romero]] film ''[[Deep Waters (1948 film)|Deep Waters]]'' (which had started on the Atlanta broadcast signal 30 minutes prior).<ref name="b&c-wtcgnational">{{cite magazine|title=Atlanta TV goes national via satellite|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=24–25|date=December 20, 1976}}</ref> Southern Satellite Systems initially charged prospective cable systems 10¢ per subscriber to transmit WTCG full-time and 2¢ per subscriber to carry it as an intermediary, post-sign-off timeshare service (from as early as midnight to as late as 6:00&nbsp;a.m. local time).<ref name="b&c-wtcgnational"/> One key legal point in Turner's contracts with programming distributors and advertisers was that they continued to charge him for programming content and commercial time as if his station were reaching only a local market. No one had thought of adding contract language to deal with satellite-delivered broadcasts of a television station to a much larger region. Turner Communications Group also chose to revise its advertising rates to better reflect WTCG's national cable audience in October 1978.<ref name="b&c-breakthrough">{{cite magazine|title=Superstation breakthrough|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=25–26|date=October 30, 1978}}</ref>

Also setting WTCG apart from other superstations that would soon follow in its footsteps was that it directly promoted its programming to its national audience, made investments in programming production as well as acquisitions, and charged separate advertising rates at the national and local levels. Given Turner's deep pockets, the station paid for syndicated programming at (albeit reasonably cheaper) rates comparable to other national networks, rather than merely receiving [[royalty payment]]s from cable systems for programs to which it held the copyright. Cable systems found WTCG—one of the few American television stations offering a 24-hour-a-day programming schedule at the time—an attractive offering as it had an extensive film library heavily reliant on classic feature films (amounting to 30 movies per week out of the 2,700 titles that Turner had accrued since taking over the station), high-profile syndicated programs and games from various Atlanta-area sports teams (including the [[Atlanta Braves]] Major League Baseball club, the [[Atlanta Hawks]] of the [[National Basketball Association|NBA]] - both of which were owned by Turner - and the [[Atlanta Flames]] of the [[National Hockey League|NHL]]). Soon after it was uplinked, an increasing number of cable television systems throughout the United States sought to carry WTCG as part of their channel lineups, ultimately making it the most widely distributed superstation for the rest of its existence under the format. By May 1978, WTCG was being received by 1.5&nbsp;million households in 45 states, with figures suggesting that its reach had been increasing at the rate of 100,000 cable households per month; by the end of that year, the station was available through cable systems in all 50 states. By July 1979, the station (by then, known as WTBS) was available to 4.8&nbsp;million cable subscribers plus an additional 556,000 households that received the station through other distribution methods (including microwave and [[Multichannel multipoint distribution service|MMDS]] services).<ref name="wapo-turner"/> 

As WTBS, the station also served to help promote Turner's subsequent cable efforts, providing simulcasts of Cable News Network ([[CNN]]) and CNN2 (later Headline News and now [[HLN (TV network)|HLN]]) upon their launches in June 1980 and January 1982, respectively, as well as offering weekend-long marathons promoting the 1992 launch of [[Cartoon Network]]. (CNN also produced the station's only conventional, long-form news effort as a superstation, the ''TBS Evening News'', a prime time newscast that ran from July 1980 to July 1984.) Aside from Turner's use of WTBS to help launch his other cable ventures, Southern Satellite Systems also distributed the [[United Press International]] (UPI) teletext news service (from 1978 to 1981) and the [[Electra (teletext)|Electra]] teletext service (from 1981 to 1993) to the [[vertical blanking interval]] (VBI) of the WTBS feed. WTBS remained the most widely distributed superstation for the rest of its existence under the format; by 1987, WTBS was available to 41.6&nbsp;million cable and satellite subscriber households nationwide. A separate feed of WTBS intended for distribution to cable providers outside the Atlanta market, incorporating national advertising substituting commercials intended for its Atlanta viewing audience, was launched in 1981. (Since the original incarnation of the syndication exclusivity rules had been repealed by that time, program substitutions on the national feed were very limited.)

===WGN, WOR and other emerging superstations===
Turner's innovation signaled the development of basic cable programming in the United States and, within three years of WTCG achieving national status, was soon copied by other common carrier firms who decided to apply for satellite uplinks to distribute other independent stations as national superstations; however, while Turner had aggressively pursued national availability for WTCG, the other superstations that would soon emerge did not purposely seek such widespread reach and were either recalcitrant about having their signals imported without consent or ignored the issue directly and allowed their newfound expanded distribution to continue unfettered.

On November 9, 1978, Chicago independent WGN-TV became America's second national superstation, when Tulsa, Oklahoma-based common carrier firm [[Gemstar–TV Guide International|United Video Satellite Group, Inc.]] – one of four applicants, along with Southern Satellite Systems, [[Lansing, Michigan]]-based American Microwave & Communications and [[Milwaukee]]-based Midwestern Relay Company, that the FCC granted approval to operate satellite transponders to relay the signal following the institution of the FCC's distant signal "open entry" policy for carrier firms – uplinked its signal onto a Satcom-3 transponder for redistribution to cable and satellite subscribers. United Video stepped in to assert uplink responsibilities as SSS had become embroiled in a transponder lease dispute with RCA American Communications in pertinence to a lawsuit involving RCA American and SSS's Satellite Communication Systems joint venture over the use of Satcom Transponder 18.<ref name="b&c-nextsuperstations">{{cite magazine|title=WGN-TV, KTVU may be the next super stations|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=30|date=October 9, 1978}}</ref><ref>{{cite magazine|title=SSS tangles with RCA over transponder for WGN-TV|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=30|date=November 6, 1978}}</ref> While TBS partnered with a satellite carrier to relay the WTBS Atlanta signal to a national audience, United Video used the legally structured loophole in the Copyright Act's compulsory license statute to uplink the signal of WGN without the prior consent of owner WGN Continental Broadcasting Company (later known as [[Tribune Broadcasting]]), a model that would be used for other superstations that emerged in the coming years. United Video did not compensate WGN directly for the retransmission of its signal, though the station and its parent company received [[royalty payment]]s from cable systems that received the United Video-fed signal for any copyrighted programming (local newscasts, public affairs shows, locally originated children's programs and sports) that WGN owned and/or produced.

The station quickly turned into a major commodity among cable systems because of WGN's telecasts of [[Chicago Cubs]] and [[Chicago White Sox]] baseball, [[DePaul Blue Demons]] college basketball, and [[Chicago Bulls]] basketball games and its locally popular in-house children's programs like ''[[The Bozo Show]]'' (the Chicago iteration of the [[Bozo the Clown]] television franchise). As the first superstation that offered long-form newscasts (compared to the newsbriefs offered by WTCG/WTBS for most of the time until 1996 as well as an abbreviated daily satirical newscast, ''17 Update Early in the Morning'', which aired from 1976 to 1979 and mixed improvisational and scripted comedy with actual news content), upon moving its late evening newscast to 9:00&nbsp;p.m. [[Central Time Zone|Central Time]] in March 1980, it also provided a prime time news alternative for viewers wanting to find out national and international headlines without having to wait for post-prime-time newscasts on local network stations, something of particular benefit to [[Snowbird (person)|snowbirds]] and other Chicago residents who temporarily or permanently relocated elsewhere in the United States. Immediately after achieving superstation status, WGN-TV became available to an estimated approximately 200 cable systems and 1.5&nbsp;million subscribers throughout the country;<ref>{{cite magazine|title=Cable Briefs: Ready customers|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=76|date=December 18, 1978}}</ref> its distribution was heavily concentrated in the [[Central United States|Central U.S.]] until the early 1980s and, by the end of the decade, had gradually expanded to encompass most of the nation with some gaps in the [[Northeastern United States|Northeastern U.S.]] that remained into the early 2010s. In 1985, Tribune—which would assume satellite distribution rights for the WGN national feed through its April 2001 purchase of the portion of United's UVTV unit that handled the feed's uplink and marketing responsibilities—began providing a direct microwave link of the WGN Chicago signal to United Video, providing it a second signal source in the event technical problems arose with the intercepted satellite signal and vice versa. WGN would become the only superstation to come close to reaching parity with WTBS, although it would continue to lag somewhat in coverage partly due to the two-year headstart of WTBS into the cable market.

[[KTVU]] (channel 2) in [[Oakland, California|Oakland]]–San Francisco followed behind on December 16, 1978, when Satellite Communications Systems uplinked the station onto a Satcom-1 transponder. (Holiday Inns Inc. would withdraw from the Southern Satellite Systems partnership by April 1979, leaving the latter to handle uplink and promotional responsibilities for KTVU.)<ref name="b&c-upintheair">{{cite magazine|title=Up in the air in more ways than one|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=60|date=December 18, 1978}}</ref><ref>{{cite magazine|title=Holiday network|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=7|date=April 16, 1979}}</ref> Despite a programming inventory comparable to other independents (including holding rights to [[San Francisco Giants]] baseball games), SCS was unsuccessful in marketing KTVU to cable systems to reach the level of WTBS, WGN-TV and WOR-TV. In April 1980, [[Warner-Amex Satellite Entertainment]] purchased the transponder space from SCS to distribute upstart music video channel [[MTV]]; KTVU's national cable distribution would be reduced to systems that already carried the station in the Western United States by early 1981.

Eastern Microwave was somewhat more successful in distributing WOR-TV (which had been available to cable and CATV systems via microwave throughout much of the Northeastern United States since 1965), when it began retransmitting the New York station's signal to cable affiliates and C-band satellite receivers throughout the remainder of the country over transponder 17 of Satcom I in April 1979. Until WOR adopted a 24-hour schedule in 1980, the satellite feed initially included a backup feed of CBS-owned New York City station [[WCBS-TV]] (channel 2) during WOR's off-hours. Even though WOR had a similar film library as other superstations (further boosted by the acquisition of the [[Universal Pictures]] film library when [[MCA Inc.]] acquired the station in a $387-million deal with the legally embattled [[RKO General]] in April 1987) and held rights to events from several New York-area professional sports teams (including the [[New York Mets]], the [[New York Rangers]], the [[New Jersey Devils]] and the [[New York Knicks]] as well as college basketball games involving [[Big East Conference]] universities), the station's distribution—while broad—was still relatively regionally scattered and paced far behind that of WTBS and WGN well into the 1990s.<ref>{{cite magazine|title=In Sync: Superstations|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=110|date=March 25, 1979}}</ref><ref>{{cite news|title=A Channel Innovates and Moves Up|url=https://www.nytimes.com/1989/09/16/arts/a-channel-innovates-and-moves-up.html|author=Jeremy Gerard|newspaper=The New York Times|date=September 16, 1989|access-date=April 29, 2019}}</ref>

United Video would eventually gain an oligopoly in superstation distribution throughout the 1980s, building on its success with WGN-TV by commencing distribution of three other superstations and handling marketing responsibilities for one more (including three that were owned by then-WGN parent Tribune Broadcasting). On May 1, 1984, United Video—which picked up the station's satellite retransmission rights from Southern Satellite Systems—uplinked the signal of WPIX to the [[Westar|Westar V]] satellite;<ref>{{cite news|title=WPIX to Join 'Superstations'|url=https://www.nytimes.com/1984/03/04/arts/wpix-to-join-superstations.html|author=Steve Knoll|newspaper=The New York Times|date=March 4, 1984|access-date=April 29, 2019}}</ref> this was followed on July 1, 1984, with its uplink of the signal of KTVT in Dallas–Fort Worth to the Satcom IV satellite, in a move undertaken by then-owner Gaylord Broadcasting to persuade cable providers that either already imported or were considering receiving the station's signal by microwave to begin transmitting the KTVT satellite feed. (United Video would later relocate KTVT's transponder to the [[Spacenet|Spacenet III]] in December 1988.)<ref>{{cite magazine|title=Another station aloft|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=10|date=April 30, 1984}}</ref><ref>{{cite magazine|title=Changing birds|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=49|date=October 24, 1988}}</ref> On October 24, 1987, Netlink—then a subsidiary of [[Tele-Communications Inc.]] (TCI)—began distributing [[KWGN-TV]] (channel 2, now a CW affiliate) over Satcom I as part of the company's "[[Denver]] 5" direct-to-home package of television stations from [[Colorado]]'s state capital that also included five default network feeds for home dish subscribers without access to a local network affiliate: NBC owned-and-operated station [[KCNC-TV]] (channel 4, now a CBS owned-and-operated station), ABC affiliate [[KUSA (TV)|KUSA-TV]] (channel 9, now an NBC affiliate), CBS affiliate [[KMGH-TV]] (channel 7, now an ABC affiliate), PBS station [[KRMA-TV]] (channel 6) and Fox affiliate [[KDVR]] (channel 31). (KWGN's satellite feed was limited in its availability to home dish users; although, at its peak, the station itself had cable carriage throughout [[Colorado Western Slope|Colorado's Western Slope]], [[Idaho]], [[Kansas]], [[Montana]], [[Nebraska]], [[New Mexico]], [[South Dakota]], [[Utah]], [[Washington (state)|Washington]] and [[Wyoming]].)<ref>{{cite magazine|title=Cablecastings: Denver addition|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=101|date=October 26, 1987}}</ref>

On February 15, 1988, Eastern Microwave Inc. began distributing WSBK-TV and KTLA (channel 5) in Los Angeles via the Satcom I-R satellite. (WSBK-TV was selected primarily for its broadcasts of [[Boston Bruins]] hockey and [[Boston Red Sox]] baseball games, while KTLA was selected for its broadcasts of [[Los Angeles Clippers]] basketball and [[Los Angeles Angels|California Angels]] baseball games.) EMI chose to encourage rather than compel cable systems in the Northeastern U.S. that already received WSBK by microwave to begin receiving the satellite feed, and outsourced marketing of the signals to home dish owners through HBO and [[Satellite Syndicated Systems|TEMPO Enterprises]]. Both superstations were notable for being the first to have their signals scrambled from the outset, using the [[Videocipher II]] encryption system as well as the second and third EMI-delivered superstations to be encrypted, after having converted the WWOR satellite signal to an encrypted format in March 1986. (Within two months of EMI making the station available via satellite, United Video assumed marketing rights for KTLA under a partnership with Eastern Microwave.) Both services had their distribution limited primarily to the home dish market, whereas their cable distribution remained confined to their respective regions ([[New England]] for WSBK and the Southwestern United States for KTLA).<ref name="b&c-twomore">{{cite magazine|title=Two more join superstation ranks|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=60|date=February 15, 1988}}</ref><ref>{{cite magazine|title=Satellite Footprints: United they stand|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=63|date=April 25, 1988}}</ref>

Unlike with WTCG/WTBS, Tribune Broadcasting (owners of WGN-TV, WPIX, KTLA and KWGN-TV until the completion of Tribune's purchase by [[Nexstar Media Group]] and concurring spin-off of WPIX to the [[E. W. Scripps Company]] in September 2019, with both successor parents inheriting the classification for those stations) and the various owners of WSBK ([[George N. Gillett Jr.|Gillett Communications]], [[Paramount Stations Group]] and [[CBS Television Stations]]) have treated their satellite-delivered stations as "passive" superstations, opting to assert a neutral position over the relay of its signal by an intermediate common carrier to a national audience and leaving national promotional duties for multichannel television services and their subscribers to the satellite carriers that retransmitted their signals; in kind, neither station received direct compensation from United Video or EMI for retransmission or promotion of their signals but received royalty payments paid by carrier cable systems to the Copyright Royalty Tribunal (CRT) for their retransmission of programs that are copyrighted in the name of the individual stations and/or their respective parent companies. This benefited the stations as it allowed them to continue paying for syndicated programming and advertising at local rates rather than those comparable to other national networks.

Even so, WGN would gradually switch to a more "active" stance in later years; Tribune began relaying the station's Chicago broadcast feed to United Video directly in 1985, and eventually acquired a majority stake in the rechristened [[TV Guide|TV Guide Inc.]]'s UVTV satellite unit in April 2001 as the company was spinning off its satellite carrier assets to focus on ''TV Guide''{{'}}s magazine, [[Pop (U.S. TV network)#History|direct-to-cable program listings]] and [[electronic program guide|interactive program guide]] services. Tribune, as a whole, had also shifted from opposing satellite retransmission of its stations sans permission to weighing in the benefits of having its stations be distributed to a wide audience, to the point of being in strong opposition against the reimposition of the syndicated exclusivity rules and filing court proceedings against major sports leagues that sought to prevent game telecasts involving local NBA and Major League Baseball teams from being imported to other media markets.<ref name="b&c-twomore"/>

===Distant signal regulation and conflicts===
During the 1960s, the FCC began to severely restrict the importation of distant signals by larger CATV and cable systems, limiting their distribution to smaller-market and rural systems, based in part on the framework of the 1963 ''Carter Mountain Transmission Corp. v. FCC'' case, which stemmed from a legal challenge by Chief Washakie TV, then-owner of KWRB-TV (channel 10, now KFNE and operating a satellite station of [[Casper, Wyoming|Casper]] Fox affiliate [[KLWY]]) in [[Riverton, Wyoming]], against the FCC license of [[Cody, Wyoming|Cody]]-based microwave relay firm Carter Mountain Transmission Corp., which intended to relay the signal of CBS/NBC affiliate [[KTWO-TV]] (channel 2) in Casper, Wyoming to CATV systems in three cities that were within the range of KWRB's off-air signal: Riverton, [[Lander, Wyoming|Lander]] and [[Thermopolis, Wyoming|Thermopolis]]. The FCC's denial of Carter's license renewal—because of its refusal to guarantee KWRB program duplication protection and the harm it would induce to the station, especially given Carter's refusal to offer the KWRB signal—was affirmed in a unanimous, three-judge decision by the [[United States District Court for the District of Columbia|U.S. Court of Appeals for the District of Columbia]] on May 24, 1963, and a consideration refusal on the case by the [[Supreme Court of the United States|U.S. Supreme Court]] on December 19.<ref>{{cite magazine|title=FCC grants five microwave protests|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=85|date=May 23, 1960}}</ref><ref>{{cite magazine|title=Microwave Denial Cites Economics|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=126–127|date=February 19, 1962}}</ref><ref>{{cite magazine|title=FCC Upheld in CATV Case|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=64|date=May 27, 1963}}</ref><ref>{{cite magazine|title=High Court Backs FCC|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=60|date=December 23, 1963}}</ref>

Further expansion of "proto-superstation" signals came through federal court rulings on separate lawsuits filed in July 1961 by [[United Artists]] and WSTV Inc. (then-owner of WSTV [channel 9, now [[WTOV-TV]]] in [[Steubenville, Ohio]]) over [[Fortnightly Corp. v. United Artists Television, Inc.|Fortnightly Corp.'s importation of television stations]] from the [[Pittsburgh|Pittsburgh, Pennsylvania]] and [[Wheeling, West Virginia]]–Steubenville, Ohio markets to its [[Fairmont, West Virginia|Fairmont]] and [[Clarksburg, West Virginia]] systems and in December 1964 by CBS (over [[TelePrompTer]]'s importation of stations from New York City, [[Albuquerque|Albuquerque, New Mexico]], [[Billings, Montana]] and [[Denver|Denver, Colorado]] to its systems in [[Elmira, New York]], [[Johnstown, Pennsylvania]] and [[Farmington, New Mexico]]).<ref>{{cite magazine|title=At Deadline: WSTV Inc. challenges CATV use of signal|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=9|date=July 10, 1961}}</ref><ref>{{cite magazine|title=CBS files suit on CATV copyright clearance|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=9|date=December 14, 1964}}</ref> In the former case, the Supreme Court ruled in a 5–1 vote on June 18, 1968, that CATV systems like Fortnightly did not incur copyright liability by retransmitting distant signals as they acted more akin to "viewers" than broadcasters;<ref>{{cite magazine|title=Is CATVs future in FCC's hands?|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=19–22|date=June 24, 1968}}</ref> the latter case, ruled on May 2, 1972, by Judge [[Constance Baker Motley]] of the [[U.S. District Court for the Southern District of New York]], affirmed that stance based on the Supreme Court's framework on the ''Fortnightly v.

On March 31, 1972, the FCC implemented a broad package of cable industry regulations passed that February, which included two rules pertaining to distant signal importation. Among the implemented rules was the original incarnation of the [[Syndication exclusivity|Syndication Exclusivity Rules]] (or "SyndEx"), which required cable providers to [[Blackout (broadcasting)|black out]] any syndicated programs carried on out-of-market stations if a television station exclusively holds the local broadcast rights to a particular program, even if the out-of-market station has the same owner as the program's claimant station. The main difference between the original Syndex law and the version enacted in 1988 was that the blackout provisions applied to almost all programming, including special event programs distributed through syndication (such as the ''[[Jerry Lewis MDA Telethon]]'' and the ''[[Easterseals (U.S.)|Easter Seals]] Telethon''). The distant signal regulations allowed cable systems in the 100 largest markets to carry imported signals as a matter of right (including the addition of two distant signals not already available in the market), restricted cable systems in smaller markets to only being able to carry three network stations and one independent station (except for undefinable markets that would not be limited in the number of carried imported signals), and instituted leapfrogging rules that required systems importing distant independent stations from the top-25 markets to choose from one or both of the two markets closest to the provider's [[city of license]] and any systems carrying the signal of a third independent being required to pick up a UHF or, if such a station is not available, VHF station located within a {{convert|200|mi|km|adj=on}} radius.<ref>{{cite magazine|title=The FCC delivers on cable|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=17, 18, 40, 44|date=February 7, 1972}}</ref> This interpretation of the rules became increasingly difficult to enforce as the number of cable-originated services increased, particularly following the emergence of communications satellites as a distribution method to the cable industry beginning in 1975.

FCC soon began outlining a regulatory framework that allowed cable systems to import some out-of-market signals without running into copyright liability. In August 1975, the agency began allowing unlimited signal importation upon either the final daily [[sign-off]] of a local "[[must carry]]" station or starting at 1:00&nbsp;a.m. ([[Eastern Time Zone|Eastern]] and [[Pacific Time Zone|Pacific Time]])/12:00&nbsp;a.m. (in all other time zones), to avoid programming conflicts with late-night programing being carried "in progress" or avoid instances in which systems would have to run a blank screen until the start of the next program. As such, the distant signal would act as a timeshare feed on a cable channel otherwise occupied by a local or out-of-market broadcast station during the occupying station's normal sign-off period.<ref>{{cite magazine|title=In Brief|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=30|date=August 25, 1975}}</ref> The last major obstacle to the creation of a national superstation was knocked down on December 19, 1975, when the FCC unanimously voted to repeal a 1972 rule requiring cable systems selecting a distant signal from among television stations in the top-25 media markets to only select a station from one of the two closest markets to the licensed system. The FCC Cable Television Bureau contended the formation of superstations was unlikely due to the absence of evidence that television stations economically benefited from cable carriage.<ref>{{cite magazine|title=Cable gets boost with deletion of leapfrogging rule|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=23|date=December 22, 1975}}</ref>

On October 1, 1976, the U.S. Congress unanimously passed the [[Copyright Act of 1976]] in separate Senate [[Voting methods in deliberative assemblies|floor]] and House [[voice vote]]s. The law provides cable systems with a compulsory license – which, under Section 111, also applies to "passive" (passthrough) satellite carriers, allowing them to retransmit "copyrighted programming from any over-the-air [television and radio] stations across the country [or, with range restrictions based on their distance from the U.S. border, from Canada or Mexico]" without seeking the originating station's express permission – that requires payment of a flat semi-annual royalty fee based both on the number of distant signals retransmitted by the system and on their total subscriber receipts (0.675% of their gross receipts for the first distant signal, 0.425% for any other signal up to the fourth and 0.2% for each signal beyond the fourth, with a separate fixed-rate exemptions for systems that have a semi-annual revenue either below $80,000 or between $80,000 and $160,000), prohibits any modifications to the imported broadcast signal and its copyrighted content (such as commercials substituted by the cable system, permitting local broadcast stations to sue the systems if violating modifications are made), and established the Copyright Royalty Tribunal, a five-member commission of the [[U.S. Copyright Office]] that is tasked with reviewing cable and other royalty rates every five years (or sooner, if changes to program exclusivity or signal importation rules are made by the FCC) and compensates eligible owners of a copyrighted program who submit a written claim to receive the mandatory royalty paid by the cable system.<ref>{{cite magazine|title=Copyright is out of Congress|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=24–25|date=October 4, 1976}}</ref><ref>{{cite web|title=Title 37: Patents, Trademarks, and Copyrights: PART 256—ADJUSTMENT OF ROYALTY FEE FOR CABLE COMPULSORY LICENSE|url=http://www.copyright.gov/title37/258.html|website=[[United States Copyright Office]]|access-date=January 11, 2015|archive-url=https://web.archive.org/web/20140527220711/http://www.copyright.gov/title37/258.html|archive-date=May 27, 2014|url-status=dead}}</ref><ref>{{cite web|title=Rate Adjustment for Satellite Carrier Compulsory License|url=http://www.copyright.gov/history/mls/ML-574.pdf|website=United States Copyright Office|access-date=January 11, 2015}}</ref> Compulsory license rules for broadcast signal distribution were extended to the home satellite industry on October 21, 1988, through the passage of [[Satellite Home Viewer Act|Satellite Home Viewer Act of 1988]], which also restricted access to network programs exclusively to home dish users in "white areas" where broadcast signals are unviewable via antenna or cable (a provision that would become pertinent to most of the remaining superstations following network launches that took place in 1995).<ref name="PassesTVRO">{{cite magazine|title=Congress, in overtime, passes TVRO, children's ad bills|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=26–28|date=October 24, 1988}}</ref>

The distribution of these superstations eventually caused conflicts between these stations and providers of similar, or identical, programming in local markets. Among the earliest opponents to the emergence of superstations was the [[Motion Picture Association of America]] (MPAA), which in 1977, with the growing distribution of WTCG, petitioned the FCC to investigate the impact of and regulate superstations amid concerns over the potential financial losses for programs that MPAA member companies distributed to other television stations, which it posited would not be offset by royalty payments by cable systems. (The MPAA, which had its inquiry petition backed by the [[National Association of Broadcasters]] [NAB] and broadcasting companies such as Kelly Broadcasting, [[McGraw-Hill|McGraw-Hill Broadcasting]] and [[Taft Broadcasting|Taft Television & Radio Company]], also lodged an unsuccessful bit to deny SSS's application to grant an expansion of WTCG's service to [[Puerto Rico]], [[Alaska]] and Canada.)<ref>{{cite magazine|title=MPAA out to stop WTCG-type spread via cable, satellite|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=20|date=August 29, 1977}}</ref><ref>{{cite magazine|title=Battle lines form as expected on petition against super stations|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=40|date=October 24, 1977}}</ref>

On October 25, 1978, the FCC implemented an "open entry" policy for satellite resale carriers wanting to feed local television stations to cable systems, a move that would pave the way for the emergence of additional superstations. The policy also commenced review on FCC applications filed by four individual satellite carriers to authorize relay of other independent stations through the [[Satcom (satellite)|Satcom]] satellite fleet:<ref name="b&c-breakthrough"/>

Reactions to the FCC's 1978 "open entry" policy ruling among program distributors ranged from "anger to passive acceptance," with concerns that satellite-distributed superstations would not adequately compensate program syndicators based on the acquired program's national availability and provide difficulty for program sales once content was sold to broadcasters in smaller markets with superstation importation via cable.<ref>{{cite magazine|title=Spreading the product|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=63|date=April 25, 1988}}</ref> Then on November 4, the FCC rescinded a provision requiring cable systems seeking a waiver of signal importation limits to prove the unique circumstances that justified the waiver, while still requiring them to show that local stations would not suffer adverse public service impacts as a result of ratings or revenue losses from the imported signal, an action that was considered a greenlight to the creation of additional national superstations.<ref>{{cite magazine|title=Distant signals closer and closer|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=24|date=November 6, 1978}}</ref>

While most superstations took on a passive stance on their distribution—programming to their local audience while benefiting tacitly from their extended distribution—a small number attempted to fight efforts to be redistributed; in March 1979, [[Metromedia]]—which was fighting an FCC grant allowing ASN Inc. (which also had been given permission to uplink WGN-TV and WOR-TV) to make KTTV an "involuntary superstation," claiming such retransmission would be a violation of a provision of Section 325 of the Communications Act that prohibited signal retransmission without a broadcaster's express consent, even though Section 111 of the 1976 Copyright Act effectively allowed such importation – asked the FCC to temporarily halt all authority for the satellite distribution and marketing of superstation signals.<ref name="b&c-panicbutton">{{cite magazine|title=Metromedia and NAB hit the FCC panic button over superstations|periodical=Broadcasting|publisher=Broadcasting Publications Inc.page=62-63|date=March 25, 1979}}</ref> Concurrent with the Metromedia petition, the NAB—later to be joined in the petition by, among others, the MPAA, the NBA, the [[National Hockey League]] (NHL), Major League Baseball [[Commissioner of Baseball|Commissioner]] [[Bowie Kuhn]], WGN Continental Broadcasting and ABC—urged the FCC to conduct an expedited rulemaking aimed at curbing "the harmful impact of superstation development on broadcast program service to the public," positing that they posed a serious threat to the ability of program producers to guarantee exclusive local rights to prospective stations seeking to buy programs being offered on the syndication market. ASN rebutted that KTTV had acknowledged the company was being authorized to redistribute its programming without distributor permission as the station could not do it on its own without shouldering liability. The issue was never fully settled, however, as ASN Inc. ceased operations amid financial issues before it could be able to retransmit KTTV's signal.<ref name="b&c-panicbutton"/><ref>{{cite magazine|title=Battle rages at FCC over reluctant superstation|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|pages=28, 33, 44, 45|date=July 23, 1979}}</ref>

The FCC repealed its remaining cable television regulations in a 4–3 vote on July 22, 1980, eliminating its restrictions on the number of broadcast stations that cable systems could carry and syndication exclusivity protections for local television stations on the basis that "local stations are not adversely affected when a cable system offers subscribers signals from television stations in other cities." The repeal of its signal importation and Syndex rules resulted in many cable systems beginning to carry other national superstations and additional regional out-of-market independents.<ref>{{cite magazine|title=FCC now all but out of cable business|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=25–27|date=July 28, 1980}}</ref> The following day (July 23), television station owner Malrite Broadcasting (later Malrite Communications) filed a lawsuit in [[United States District Court for the Eastern District of New York|United States Court of Appeals for the Eastern District of New York]] to stop the rules from going into effect.

Interpretations of the copyright act also led to legal cases against superstation distributors. In April 1981, Tribune Broadcasting filed a [[copyright infringement]] suit against United Video in the [[United States District Court for the Northern District of Illinois]], on grounds that United inserted teletext content from its [[Dow Jones & Company|Dow Jones]] business news service over the satellite feed's [[vertical blanking interval]] (VBI) during retransmissions of WGN's newscasts and other local programs in place of the teletext [[TV listings|listings]] data that the station was relaying to United's Electronic Program Guide (EPG) service (later Prevue Guide and now the entertainment-based [[Pop (U.S. TV network)|Pop]]) in violation of the Copyright Act's passive carrier rules.<ref name="b&c-interpretcopyright">{{cite magazine|title=Interpreting the copyright act|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=57|date=May 4, 1981}}</ref><ref>{{cite magazine|title=Sticky issue in WGN-United Video case|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=89|date=September 7, 1981}}</ref> In October 1981, District Court Judge Susan Getzendanner denied an injunction to WGN Continental Broadcasting and dismissed the United Video case, determining that United was not required to carry the station's teletext transmission.

The MPAA, the NAB (despite its insistence that the CRT had limited to no authority to set rates outside the mandatory five-year interval), sports leagues and other copyright holders soon asked the Copyright Office to hike its royalty rates to compensate for the loss of the distant signal carriage and syndication exclusivity deregulation.<ref>{{cite magazine|title=Washington Watch: Copyright request|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=58|date=September 21, 1981}}</ref><ref>{{cite magazine|title=Washington Watch: NAB backs MPAA|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=74|date=October 12, 1981}}</ref> On October 22, 1982, the Copyright Royalty Tribunal instituted a statutory license rate adjustment, establishing a 3.75% royalty fee of a cable system's gross receipts from subscribers (if their semi-annual revenue exceeds $214,000) for carriage of each previously impermissible distant signal and a SyndEx surcharge for programs transmitted on a previously blackout-subjected imported signal that was added after the rules were repealed, alongside existing royalties paid to the CRT "Basic Fund". The increase met with backlash from cable industry executives and lobbyists, led by [[NCTA (association)|National Cable Television Association]] (NCTA) President [[Tom Wheeler (FCC)|Tom Wheeler]], who were concerned that it would result in the removal of superstations and other distant signals as well as harm independent stations supported by the extended audience.<ref>{{cite magazine|title=Cable industry mounting counterattack on CRT|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=24–25|date=November 22, 1982}}</ref> By the time the fees were imposed on March 15 (which was dubbed by cable systems as "Black Tuesday for Cable Viewers"), NCTA estimates showed that about 6.3&nbsp;million subscribers nationwide had lost access to one or more distant signals because of defections by cable systems that wanted to avoid paying the increased copyright fees. Dating back weeks prior to the deadline (as some systems chose to remove imported signals after the CRT delayed the fee imposition), various distant signals experienced a combined loss of 493 cable clearances, with WTBS, WGN-TV and WOR-TV making up half the defections with a combined loss of 249 clearances. Other cable-originated services benefited from the fee increases and distant signal defections, with the Cable Health Network (CHN; merged with Daytime in 1984 to form [[Lifetime (TV network)|Lifetime]]) experiencing the most growth; by March 1983, 1.2&nbsp;million of the 9.1&nbsp;million subscribers that CHN had at the time came from cable systems that replaced a distant signal with the channel. (Later estimates showed that WTBS lost 320,000 subscribers, while Eastern Microwave recouped around 200,000 subscribers for WOR and United Video recouped around 600,000 of its CRT-related losses of 1.2&nbsp;million subscribers by May 1983.)<ref>{{cite magazine|title=Black Tuesday descends on cable industry|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=61–62|date=March 21, 1983}}</ref><ref>{{cite news|title=How Copyright Fees Affect Cable TV|url=https://www.nytimes.com/1983/03/19/arts/how-copyright-fees-affect-cable-tv.html|author=Sally Bedell|newspaper=The New York Times|date=March 19, 1983|access-date=May 6, 2019}}</ref><ref>{{cite magazine|title=Closed Circuit: False alarm?|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=7|date=May 2, 1983}}</ref>

On May 18, 1988, the FCC passed a new version of the Syndication Exclusivity Rights Rule. The new policy—spurred in part by a 1987 study conducted by the Association of Independent Television Stations (INTV), which provided evidence that programming duplication between superstations and local stations created significant ratings dilution for the latter group in certain time periods and a resulting significant loss of advertising revenue—not only allowed television stations to claim local exclusivity over syndicated programs (even if the out-of-market station has the same owner as the station with that particular exclusive program) and required cable systems to black out claimed programs; it also granted cable systems or carrier firms the ability to secure an agreement with the claimant station or a syndication distributor to continue carrying a claimed program through an out-of-market station, allowing some superstations to acquire partial or exclusive national cable rights to certain programs. The law also closed the [[terrestrial loophole]] that allowed superstations like WGN and WTBS to continue paying local single market rates for programming acquisitions even as they were gaining national coverage, whilst selling that extended coverage to advertisers; this change made it so that other local stations which had their signals beamed to a satellite transponder – whether willingly or not – were charged appropriately for program content based on their actual national distribution, depending on arrangements with any given syndicator.<ref>{{cite magazine|title=Syndex redux: FCC levels the playing field|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=31–33|date=May 23, 1988}}</ref><ref>{{cite news|title=FCC Reimposes Rule On TV Exclusivity|url=http://articles.chicagotribune.com/1988-05-19/business/8803180484_1_fcc-chairman-dennis-patrick-exclusivity-rules-superstations|author=Charles Storch|newspaper=Chicago Tribune|publisher=Tribune Publishing|date=May 19, 1988|access-date=May 6, 2019}}</ref><ref>{{cite news|title=FCC Reinstates Exclusive Rights|url=https://articles.latimes.com/1988-05-18/news/mn-2996_1_exclusive-rights|agency=[[Reuters]]|newspaper=Los Angeles Times|date=May 18, 1988|access-date=May 6, 2019}}</ref><ref>{{cite news|title=Same reruns on too many channels?

A major concern brought about by the new rules was that it would force cable systems to drop certain superstations altogether, rather than shoulder expenses that would be incurred with the resultant blackouts and any responsibilities for acquiring substitute programming, thereby denying viewers access to sporting events popular among subscribers who received those signals. In preparation for the policy's implementation – which took effect on January 1, 1990, after FCC-enforced delays in the regulation's rollout – some superstations decided to indemnify cable systems from potential blackouts by ensuring that, at least, some programs that could be subjected to local syndication exclusivity claims could continue to be shown to their national audience, so as to prevent the loss of sports access. WTBS effectively limited the number of necessary blackouts or substitutions by licensing the majority of its programming for carriage on both its national and Atlanta area feeds. (Certain local programs carried by the station, such as public affairs and educational children's programs, were not carried on the TBS national feed, but these omissions were because those programs were strictly intended to fulfill local obligations for public affairs content.)<ref>{{cite magazine|title=Making WTBS 'blackout-free'|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=40–41|date=July 31, 1989}}</ref>

United Video and Eastern Microwave respectively opted to devise standalone national feeds of WGN and WWOR, each incorporating an alternate schedule differing from the local broadcast signal to some degree—comprising both programs aired by the parent station for which the companies were able to secure the national retransmission rights (including some held over from before the SyndEx law was enacted), and supplementary programs acquired specifically for the national cable feed to absolve any holes caused by exclusivity claims—as well as separate national advertising, and in the case of WWOR, local advertising sold by individual cable systems. This would be achieved by "splitting" the signal, often requiring the use of a separate transponder to switch between the local feed and the alternate programming feed, so that certain programs viewed in the station's home market could be easily replaced with separate content that would only be shown over the national cable feed.<ref>{{cite magazine|title=United Video and WGN-TV to keep station syndex-proof|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=31|date=February 6, 1989}}</ref><ref>{{cite magazine|title=Operators Get Avails on WWOR|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=39–40|date=August 19, 1991}}</ref> While United Video made efforts to clear as much of the programming seen on the WGN Chicago feed as it possibly could, EMI increasingly filled the national [[WWOR EMI Service]] feed with library content distributed by [[Universal Television]], [[MGM Television]] and [[Quinn Martin]]—consisting of classic television series from the 1950s to the 1970s—as well as select programs from the ''[[Christian Science Monitor]]'' television service, alongside shows on WWOR's local program schedule that it was able to acquire retransmission rights at the national level (including local newscasts, sports and other WWOR-produced programming as well as special events, the station's overnight simulcast of the [[Shop at Home Network]] and a limited number of syndicated shows that did not have exclusivity claims in any market). Confusingly for WWOR's national cable viewers, on-air [[Promo (media)|promotions]] for programs not contracted to air nationally over the EMI Service were shown unaltered during simulcasts of programs aired on the New York signal. (This was not an issue with the WGN national feed, as United Video chose to substitute program promotions for shows airing on the Chicago signal that were not cleared on the national feed with those for the replacement shows exclusively seen on the latter, albeit still using station logos and promotional graphics used by the Chicago broadcast feed).

To blunt potential subscriber complaints over widespread programming blackouts, many cable systems removed both regional and quasi-national superstations (like WSBK, WPIX and KTVT) as well as other distant signals that their satellite carriers were unable or unwilling to take immediate steps to ensure their programming was "Syndex-proofed" to avoid blackouts. WGN and WTBS saw little negative impact to their distribution following the Syndex implementation, with WGN actually heavily benefiting from provider removals of other superstations (including then sister station WPIX) during the early 1990s, allowing for further expansion of its distribution reach. EMI estimated simultaneous losses of 500,000 subscribers and an increase of around one million households to its cable distribution of WWOR, the latter being attributed to some local cable systems adding the Syndex-proof WWOR EMI Service feed. Most complaints over the removal of some regional and quasi-national superstations were because of the loss of access to coverage from regional professional sports teams (such as the [[Boston Red Sox]] via WSBK, the [[Texas Rangers (baseball)|Texas Rangers]] and [[Dallas Mavericks]] via KTVT and the New York Yankees via WPIX), leading some systems to resort to cherrypicking sports from the removed superstations to mollify subscribers and local politicians acceding to complaints from their constituents by pushing other cable systems to seek solutions to resume sporting events lost through the removal of those superstations. (For example, amid public pressure from the Providence City Council and Rhode Island Department of Public Utilities and Carriers, Dimension Cable Services's [[Providence, Rhode Island]] system [now operated by [[Cox Communications]]], which removed the 24-hour WPIX feed upon the Syndex rollout, began placing the station's Yankees telecasts on a local origination channel in May 1990, in exchange for paying United Video full-time copyright fees.)<ref>{{cite news|title=Local Stations Undergo Format Switch|url=https://www.dailypress.com/news/dp-xpm-19891125-1989-11-25-8911210272-story.html|author=Joseph Pryweller|newspaper=[[Daily Press (Pennsylvania)|Daily Press]]/[[The Times-Herald]]|publisher=Tribune Publishing|date=November 25, 1989|access-date=May 6, 2019}}</ref><ref>{{cite magazine|title=Returns coming in after week one of syndex|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=137|date=January 9, 1990}}</ref><ref>{{cite magazine|title=Cherrypicked Answer To Baseball Blackout|author=Andy Grossman|periodical=Channels|publisher=C.C.

The passage of the [[Satellite Home Viewer Act|Satellite Home Viewer Act of 1988]] on October 19, 1988, extended the compulsory license to direct-to-home (DTH) satellite services, protecting distribution of broadcast signals to dish owners under existing copyright statutes. (The act's provisions primarily benefited so-called "affiliate superstations," provided that the distant network stations could only be distributed to "unserved households" that were unable to receive a local affiliate off-air.)<ref name="PassesTVRO"/><ref>{{cite news|title=Network-SBN litigation all but settled by superstation bill|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=56|date=October 30, 1988}}</ref> For many years after the passage of SyndEx for cable systems, the satellite television industry remained exempt from syndication exclusivity regulations, resulting in subscribers of direct broadcast satellite and C-Band providers continuing to be able to view all programming seen on the local broadcast signals of national and regional superstations (except where the provider already offered the SyndEx-compliant cable feed). An FCC inquiry on whether SyndEx rules should be applied to home dish services concluded in January 1991 that extending those rules to satellite "would be technically and economically infeasible" as equipment that would allow programs to be selectively blacked out based on the media market would not likely be marketed until after the initial compulsory license expired in 1994 and that the expense of "preventing viewing by a relatively few authorized home satellite dish owners for a relatively short period" would be greater than that incurred by cable providers.<ref>{{cite magazine|title=FCC Says No to Home Dish SyndEx|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=56|date=January 28, 1991}}</ref>

Copyright laws pertaining to broadcast signal carriage by satellite providers were eventually overhauled through amendments to the Communications Act of 1996 that were added through the November 1999 implementation of the Satellite Home Viewer Improvement Act (SHVIA), which allowed satellite providers to carry local broadcast signals on the Congressionally-suggested condition that the FCC develop rules protecting the sports, network and syndicated programming rights of local broadcasters. On November 2, 2000, the FCC approved identical network non-duplication, syndication exclusivity and sports blackout rules applying to the six FCC-designated national superstations (WGN-TV, KTLA, WPIX, KWGN-TV, WSBK-TV and WWOR-TV) and, in the case of the sports blackouts, other distant signals retransmitted over home dish units to an extent where it would be "technically feasible and not economically prohibitive;" this statute would eventually limit distribution of the five [[grandfather clause|grandfathered]] stations to rural areas without distributors of similar programming. The rules, which took effect on November 30 and also applied to satellite common carriers that uplinked and distributed the superstations, gave satellite providers at least four months to implement duplication protections for network and syndicated programs and 60 days notice to comply with sports and programming blackout requests. An exemption to the Communications Act's [[retransmission consent]] statute in the SHVIA rules allowed satellite carriers to retransmit a superstation signal absent the station's prior written consent under the latter two aspects of the aforementioned FCC-defined "national superstation" criteria, provided that the service complies with the non-duplication, syndication exclusivity and sports blackout rules. (TBS was not covered under the SHVIA's de facto distant signal grandfathering clause as its national feed was considered a technically separate entity from its over-the-air parent feed in Atlanta. The act's network non-duplication and Syndex rules were thought to negatively affect the distribution of WGN as its national feed was compliant with those restrictions.)<ref>{{cite web|title=Commission Implements Satellite Home Viewer Improvement Act Sports Blackout and Program Exclusivity Rule Provisions for Satellite Carriers|url=https://www.fcc.gov/Bureaus/Cable/News_Releases/2000/nrcb0024.txt|publisher=Federal Communications Commission|date=November 2, 2000|access-date=May 6, 2019}}</ref><ref>{{cite web|title=Local TV gets shield from DBS|url=https://www.broadcastingcable.com/news/local-tv-gets-shield-dbs-95331|author=Bill McConnell|periodical=Broadcasting & Cable|publisher=Cahners Business Information|page=8|date=November 6, 2000|access-date=May 6, 2019}}</ref><ref>{{cite news|title=FCC's Rules Cut TV Offerings of 2 Satellite Firms|url=https://www.latimes.com/archives/la-xpm-2000-nov-03-fi-46268-story.html|agency=Bloomberg News|newspaper=[[Los Angeles Times]]|date=November 3, 2000|access-date=May 6, 2019}}</ref><ref>{{cite web|title=FCC Adopts Network Nonduplication, Syndicated Exclusivity and Sports Blackout Rules for Satellite Carriers|url=https://www.dwt.com/advisories/FCC_Adopts_Network_Nonduplication_Syndicated_Exclusivity_and_Sports_Blackout_Rules_for_Satellite_Carriers_11_09_2000/|website=Davis Wright Tremaine LLP|date=November 9, 2000|access-date=May 6, 2019}}</ref><ref>{{cite web|title=FCC sets sat blackout rules; New law affects EchoStar, DirecTV programming|url=https://variety.com/2000/biz/news/fcc-sets-sat-blackout-rules-1117788684/|author=Pamela McClintock|periodical=[[Variety (newspaper)|Variety]]|publisher=Cahners Business Information|date=November 2, 2000|access-date=May 6, 2019}}</ref> The Satellite Home Viewer Extension and Reauthorization Act (SHVERA), signed into law on December 8, 2004, allowed satellite providers to carry "[[significantly viewed]]" superstations and distant network signals to subscribers royalty-free and with the payment of retransmission consent, provided that the subscriber also receives local stations from the provider, and permitted providers to deliver superstations to commercial businesses.<ref>{{cite web|title=Congress Extends and Amends Compulsory Copyright License for Satellite Delivered Superstations and Distant Network Stations|url=https://www.dwt.com/advisories/Congress_Extends_and_Amends_Compulsory_Copyright_License_for_Satellite_Delivered_Superstations_and_Distant_Network_Stations_12_16_2004/|website=Davis Wright Tremaine LLP|date=December 16, 2004|access-date=May 1, 2019}}</ref>

==== Conflicts with professional sports leagues ====
Much of the appeal of superstations to viewers came from the national carriage of sporting events involving professional league teams that contracted their telecasts to the originating stations within home markets. Although professional sports teams benefited heavily from their national exposure—especially with regards to WTCG/WTBS's carriage of the Atlanta Braves and the Atlanta Hawks, and WGN-TV's broadcasts of sporting events featuring the Chicago Cubs, Chicago White Sox and Chicago Bulls—superstation broadcasts of [[National Basketball Association]] (NBA) and [[Major League Baseball]] (MLB) games were met with resistance from league commissioners, who contended these telecasts—regardless of the positive effects on team loyalty—diluted the value of their national television contracts with other broadcast and cable networks. Some superstation operators (like Ted Turner and former [[Tribune Media|Tribune Company]] vice president John Madigan) note a lack of corroborating evidence of any negative effects on game attendance and league revenue, suggesting that sports leagues have used superstation telecasts of their games as a scapegoat for financial problems incurred by the league caused by other factors such as the performance of certain teams and management issues.<ref>{{cite news|title=Baseball on Cable-TV Still Has Fuzzy Image|url=https://www.latimes.com/archives/la-xpm-1987-04-19-sp-2113-story.html|agency=United Press International|newspaper=Los Angeles Times|date=April 19, 1987|access-date=May 6, 2019}}</ref>

The only federal restrictions applying to sports events shown on superstations and other imported signals was the so-called "same-game rule," enacted by the FCC in June 1975 to prohibit cable systems from retransmitting a sports event through a distant signal within a {{convert|35|mi|km|0}} zone around the city of the home team's arena if the game is not airing on a local television broadcaster, with a subsequent amendment requiring the broadcast rights-holder to inform local cable systems of game deletions no later than Monday of the preceding calendar week of the proposed deletion. (Other leagues had proposed a broader blackout zone: the [[National Hockey League]] [NHL] suggested that the protection zone should be extended across a team's entire home market, while the [[National Football League]] [NFL] and Major League Baseball each advocated for a {{convert|75|mi|km|adj=on}} zone, with the latter also seeking a {{convert|20|mi|km|adj=on|disp=sqbr}} zone around the cities of [[Minor League Baseball|minor league]] franchises and a {{convert|35|mi|km|adj=on|disp=sqbr}} zone around a team's local television rights-holder.)<ref>{{cite magazine|title=FCC on course for adopting same-game rule for importation of distant sports|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=30|date=June 30, 1975}}</ref><ref>{{cite magazine|title=Same-game rule is out of bounds, say sports, broadcasters|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=63|date=September 1, 1975}}</ref><ref>{{cite magazine|title=For the Record|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=73|date=November 17, 1975}}</ref> The major professional sports leagues eventually imposed their own broadcasting restrictions around the number of games that could air annually on any out-of-market stations, which resulted in superstations sometimes substituting sports events with syndicated programming and feature films in adherence. (This had an adverse effect on WGN, WWOR and WPIX, which each had news departments, as some of their respective newscasts would be subjected to substitutions if a sports event—particularly one shown during prime time—was preempted.)

One of the first known legal efforts to challenge superstation telecasts of sports events came in April 1981, when Eastern Microwave Inc. filed a declaratory judgement inquiry in the [[United States District Court for the Northern District of New York]], contending that its cable retransmissions of WOR's New York Mets telecasts did not constitute copyright infringement. Mets owner [[Doubleday (publisher)|Doubleday Sports Inc.]] contended it had the right to control the telecasts outside of its home market and informed EMI that the telecasts would be recorded upon transmission, effectively subjecting them to copyright by Doubleday; EMI contended that it was exempt from paying royalties for the telecasts under Section 111 (a) (3) of the Copyright Act, which contends that the secondary transmission of a program by an intermediary carrier did not infringe upon a copyright if the carrier had "no direct or indirect control over the content or selection of the primary transmission or over the particular recipients of the secondary transmission," and if the carrier's transmission activities only pertained to providing "wires, cables or other communications channels for the use of others."<ref name="b&c-interpretcopyright"/> On March 12, 1982, District Judge [[Neal Peters McCurn|Neal P. McCurn]] ruled that EMI and other satellite carriers were liable for royalty payments to program suppliers. The [[United States Court of Appeals for the Second Circuit]] (in a reversal of the Central District Court decision on October 20) and the Supreme Court (in a February 25, 1983, decision refusing review of the case) both concurred with EMI's arguments, holding that the company constituted as a "passive" carrier exempt from copyright fee payments—along with noting that EMI had only one available transponder for its extraterrestrial services and "naturally" sought to re-transmit "a marketable station"—under the Copyright Act's existing structure.<ref>{{cite magazine|title=Judge's ruling in Eastern Microwave case muddies copyright waters|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=73|date=March 22, 1982}}</ref><ref>{{cite magazine|title=Court reverses Eastern Microwave|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|pages=73–74|date=May 24, 1982}}</ref><ref>{{cite magazine|title=Eastern Microwave cleared by Supreme Court|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|page=73|date=May 24, 1982}}</ref>

Outside of the teams that benefited from the broader exposure the telecasts gave them, Major League Baseball had long felt that superstations ate into their ability to gain revenue from agreements with national networks like ESPN. (As a comparison, in 1992, ESPN televised 175 baseball games as part of a broader $100-million-per year deal at a per-game cost of $571,428, about 12 times more than what TBS, WGN, WWOR and WPIX paid cumulatively for their respective team-based packages that year, encompassing a combined 435 games for an annual fee of $20&nbsp;million or a per-game cost of $46,000). A succession of three MLB Commissioners—which, among the position's responsibilities, handles negotiations for all national broadcasting contracts but is prohibited under the federal compulsory license law from controlling carriage of superstation telecasts—attempted to curb the telecasts or convince superstations to pay a higher fee for the national telecasts to varying success. After Bowie Kuhn was appointed Commissioner in 1981, team owners lobbied the league to place a tax on superstation telecasts; the proposed tax passed in a 24–2 vote (with the Braves and the Cubs dissenting). Other legal attempts by Kuhn and league management to reduce the superstation telecasts ultimately failed because of federal copyright laws that protected the broadcasts. The tax was implemented in January 1985, under successor [[Peter Ueberroth]], with Ted Turner becoming the first MLB team owner to agree to the revenue-sharing plan, under which he made annual contributions to the league's Central Fund for the continued right to carry Braves baseball games over WTBS. The Tribune Company (then-owner of WGN and WPIX, the former of which cited its absent accounting of its national cable audience in its advertising rates for its initial participation reluctance, as well as the Cubs), [[MCA Inc.]] (then owner of WWOR) and Gaylord Broadcasting (then owner of KTVT) soon each agreed to contribute to the fund for the right to air Cubs, White Sox, Yankees, Mets and Rangers games outside the teams' respective home markets. (The total payment reflected the reach of each superstation; by 1992, Turner and the Cubs paid $12&nbsp;million and $6&nbsp;million, respectively, reflecting WTBS's 58-million subscriber audience and WGN's 35 million subscribers at the time, whereas WWOR and WPIX each chipped in only $1&nbsp;million, better reflecting their more regionalized distribution.).<ref>{{cite magazine|title=Turner and baseball come to terms|periodical=Broadcasting|publisher=Broadcasting Publications Inc.|pages=33–34|date=January 28, 1985}}</ref><ref>{{cite news|title=Ueberroth: Superstation are Hazardous to Baseball's Health|url=https://www.orlandosentinel.com/news/os-xpm-1985-04-07-0290070043-story.html|author=Russ White|newspaper=[[Orlando Sentinel]]|publisher=Tribune Publishing|date=April 7, 1985|access-date=May 6, 2019}}</ref><ref>{{cite news|title=What's Good for Ted Turner May Not Be So Super for Us: WGN|url=https://www.chicagotribune.com/news/ct-xpm-1985-01-29-8501060379-story.html|author=Skip Myslenski|newspaper=Chicago Tribune|publisher=Tribune Publishing|date=January 29, 1985|access-date=May 6, 2019}}</ref><ref>{{cite news|title=Vincent Tries a Little Tenderness|url=https://www.chicagotribune.com/news/ct-xpm-1992-06-21-9202250151-story.html|author=Jerome Holtzman|newspaper=Chicago Tribune|publisher=Tribune Publishing|date=June 21, 1992|access-date=May 6, 2019}}</ref>

Concerns by many of Major League Baseball team owners that the share would be used to buoy the expansion of KTVT into a fourth national superstation (a move that would have had to be undertaken by United Video as it was the station's satellite redistributor), American League team owners voted down Gaylord Broadcasting President [[Edward L. Gaylord]]'s initial bid to purchase 33% of the Texas Rangers on January 11, 1985, in a 9–5 confirmation vote (below the two-thirds votes needed to approve the sale). Ueberroth would invoke a "best interests of baseball" clause on February 8 to approve the sale and associated broadcast contract with KTVT, which required Gaylord Broadcasting to pay re-transmission fees for games that the station televised outside of its six-state cable footprint.<ref>{{cite magazine|title=Telecastings: Struck out|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|pages=99–100|date=January 28, 1985}}</ref><ref>{{cite magazine|title=In Brief|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=96|date=February 11, 1985}}</ref><ref>{{cite news|title=Officials Feel Gaylord to Get OK on Rangers|url=https://newsok.com/article/2094444/officials-feel-gaylord-to-get-ok-on-rangers|author=Volney Meece|newspaper=The Oklahoman|publisher=Oklahoma Publishing Company|date=January 12, 1985|access-date=May 6, 2019}}</ref><ref>{{cite news|title=Ueberroth Approves Gaylord-Rangers Deal|url=https://newsok.com/article/2097646/ueberroth-approves-gaylord-rangers-deal|author=Jerry McConnell|newspaper=The Oklahoman|publisher=Oklahoma Publishing Company|date=February 9, 1985|access-date=May 6, 2019}}</ref><ref>{{cite news|title=Rangers' New Owners Not Planning Changes|url=https://newsok.com/article/2152637/rangers-new-owners-not-planning-changes|author=Jerry McConnell|newspaper=The Oklahoman|publisher=Oklahoma Publishing Company|date=July 5, 1986|access-date=May 6, 2019}}</ref> Similar issues also prevented Gaylord from buying the 58% interest by majority-owner [[Eddie Chiles]], a share that Chiles would ultimately sell in a $46-million deal to an ownership group led by eventual [[Governor of Texas|Texas Governor]] and U.S. President [[George W.

Ueberroth's successor, [[Fay Vincent]], took a more hard-line approach against baseball telecasts shown over superstations. During his two-year tenure as league commissioner, he tried to introduce contract language in local broadcast agreements that would allow a team to terminate the contract if broadcasts were re-transmitted "by any means" to more than 200,000 homes outside the team's territory, launched a petition to the FCC to redefine how its non-duplication rules constitute a "network program" to force cable systems to blackout superstation-licensed live sports broadcasts, and asked Congress for the repeal the compulsory copyright license and the inclusion of an amendment to the [[Cable Television Consumer Protection and Competition Act of 1992]] that would force superstations to enforce blackouts of sporting events if a conflict occurred with a local telecast of the same game. (The latter amendment spurred an on-air campaign by Turner Broadcasting, which saw responses, mostly opposed to the proposed legislation, by more than 17,000 viewers.)<ref>{{cite magazine|title=Baseball Asks FCC for Local Exclusivity Against Superstations|periodical=Broadcasting|publisher=Cahners Business Information|page=95|date=September 10, 1990}}</ref><ref>{{cite magazine|title=In Brief|periodical=Broadcasting|publisher=Cahners Business Information|page=97|date=October 8, 1990}}</ref><ref>{{cite magazine|title=NCTA, Superstations Take Swing at Baseball's Exclusivity Protection Pitch|periodical=Broadcasting|publisher=Cahners Business Information|page=83|date=October 15, 1990}}</ref><ref>{{cite magazine|title=It's Root, Root, Root for the Out-of-Town Team|periodical=Broadcasting|publisher=Broadcasting Publications, Inc.|page=24|date=August 10, 1992}}</ref><ref>{{cite news|title=Vincent Blasts Superstations|url=https://www.chicagotribune.com/news/ct-xpm-1992-04-30-9202080473-story.html|newspaper=Chicago Tribune|publisher=Tribune Publishing|date=April 30, 1992|access-date=May 6, 2019}}</ref><ref>{{cite news|title=TV: Vincent's Two-Way Problem|url=https://www.chicagotribune.com/news/ct-xpm-1992-08-28-9203180654-story.html|author=Steve Nidetz|newspaper=Chicago Tribune|publisher=Tribune Publishing|date=August 28, 1992|access-date=May 6, 2019}}</ref> Then in July 1992, in a move seen by some as targeting the Cubs' WGN telecasts, Vincent ordered a realignment of the [[National League (baseball)|National League]] (NL) that sought to move the Chicago Cubs and the [[St. Louis Cardinals]] to the [[National League West]] and the Atlanta Braves and the [[Cincinnati Reds]] to the [[National League East]] starting with the 1993 season. Tribune staunchly opposed the proposed realignment, filing a [[breach of contract]] lawsuit accusing Vincent of overstepping his authority in ordering the realignment and arguing it would dilute existing team rivalries. (The realignment proposal also sparked concerns that local advertising revenue for WGN's prime time newscast would be depressed by frequent post-9:00&nbsp;p.m. <nowiki>[</nowiki>[[Central Time Zone|Central Time]]<nowiki>]</nowiki> delays during the regular season from an increased number of Cubs games involving [[Pacific Time Zone]]-based Western Division teams starting in the late evening in the eastern half of the country.

U.S. District Judge [[Suzanne B.

The NBA also undertook actions to limit superstation telecasts of the league's games. In 1982, it began prohibiting television stations that reached at least 5% of all out-of-market cable households from airing games that conflicted with those shown on the league's national cable partners (at the time, [[NBA on ESPN|ESPN]] and [[NBA on USA|USA Network]]); this transitioned in June 1985 to a 25-game limit on the number of seasonal NBA telecasts that could be licensed to superstations (sixteen fewer than the 41-game maximum under existing NBA local broadcast rules).<ref>{{cite news|title=N.B.A. Expansion Unlikely for 1986–87|url=https://www.nytimes.com/1985/06/27/sports/nba-expansion-unlikely-for-1986-87.html|newspaper=The New York Times|date=June 27, 1985|access-date=May 6, 2019}}</ref> Concerned with the potential impact that the concurring returns of the Chicago Bulls and the Atlanta Hawks to WGN and WTBS, respectively, would have on its national contracts with [[NBA on NBC|NBC]] and ESPN, in April 1990, NBA Commissioner [[David Stern]] further reduced the amount of superstation-licensed NBA telecasts to 20 games per season. This sparked a 5½-year legal battle against the NBA by Tribune Broadcasting and Chicago Bulls parent Chicago Professional Sports L.P. The conspiracy and antitrust lawsuit filed by the co-plaintiffs in the [[United States District Court for the Northern District of Illinois]] on October 16, 1990, alleged that the 20-game limit was aimed at "phas[ing] out such superstations telecasts entirely in increments of five games each year over the next five years," a separate plan proposed by Stern that was never voted upon by NBA team owners.

===Evolution and decline; the remaining superstations===
Even though superstations remained reasonably popular among cable and satellite subscribers, in no small part because of team-based sports broadcasts, various changes to the television industry beginning in the 1990s—especially the proliferation of cable-originated program services and the resultant increase in original programming produced by many cable channels—as well as existing distant signal policies—such as the syndication exclusivity rules—precipitated the decline in their viability. As early as 1986, with the launch of the Fox Broadcasting Company, a handful of the intrastate superstations – such as [[KMSP-TV]] (channel 9, now a Fox owned-and-operated station) in [[Minneapolis]]–[[Saint Paul, Minnesota|St. Paul]], [[KSHB-TV]] (channel 41, now an NBC affiliate) in [[Kansas City, Missouri|Kansas City]] and [[WKBD-TV]] (channel 50, now a CW owned-and-operated station) in Detroit—that continued to maintain reasonable out-of-market distribution after the March 1983 copyright royalty increase had terminated their carriage agreements with cable providers beyond their home markets because of the presence of local independent stations that were able to serve as prospective Fox affiliates in many of the areas within the imported stations' remaining distribution footprint. Additional decline in the availability of intrastate superstations came in the mid-1990s, when many of the remaining regional superstations let their carriage agreements expire or terminated them outright amid [[1994–96 United States broadcast TV realignment|local network affiliation shuffles]] that caused stations such as KTVT, KSTW and [[KPHO-TV]] (channel 5, now a CBS affiliate) in [[Phoenix, Arizona|Phoenix]] taking on affiliations with one of the [[Big Three television networks|Big Three]] networks (ABC, CBS or NBC), as contractual and federal restrictions prevented them from maintaining regional distribution upon becoming major network affiliates.

Very few of these stations reduced their distribution as a result of taking affiliations with either the United Paramount Network ([[UPN]]) or [[The WB|The WB Television Network]]. In fact, in December 1993, [[WarnerMedia|Time Warner]] permitted Tribune Broadcasting and United Video to have WGN-TV—which initially had intended to maintain a limited, if any, relationship with the network—act as a de facto national feed for The WB to cover smaller and mid-sized markets where extra time was needed for the network to fill absences in local affiliate coverage. (The Tribune Company held minority ownership in The WB from August 1995 until the founding of successor The CW in January 2006, when the company relinquished its interest to avoid partially shouldering The WB's shutdown expenses.) Station management had expressed concerns over the potential negative impacts fulfilling commitments to the network's soon-to-be-expanded program offerings would have on its sports broadcast rights and, by association, its national distribution; Time Warner rectified those issues by agreeing to reduce the network's initial schedule to one night per week (from two) in exchange for leasing airtime on the WGN national feed.<ref>{{cite magazine|title=WB network signs WGN-TV|author=Joe Flint|periodical=Broadcasting & Cable|publisher=[[Reed Business Information|Cahners Business Information]]|page=14|date=December 6, 1993}}</ref><ref>{{cite news|title=WGN Affiliation for New Network|url=https://www.chicagotribune.com/news/ct-xpm-1993-12-04-9312040167-story.html|author=J.

The downside of the Paramount decision was that, from January 1995 until over-the-air [[digital subchannel|digital multicasting]] became viable in the first half of the 2000s, it left most or all UPN programming unavailable in some mid-sized and most smaller markets where the network was not able, at least initially, to gain even secondary affiliate clearances.

WWOR—although it technically never gave up its superstation status—ceased distributing a national cable feed on December 31, 1996, a move made by [[Advance Publications#Former and defunct divisions|Advance Entertainment Corporation]] (which assumed ownership of corporate cousin Eastern Microwave Inc. and its satellite distribution rights to WWOR and WSBK-TV earlier in 1996) to avoid having to pay an increased royalty fee for the first six months of 1997 that the Copyright Royalty Tribunal instituted on January 1, 1997. To the consternation of many cable systems because of how it marketed the action, weeks before the WWOR EMI Service was to be discontinued, [[Discovery Communications|Discovery Networks]] quickly purchased the feed's satellite transponder slot from Advance Entertainment to expand distribution of the fledgling [[Animal Planet]] network. About 12.5&nbsp;million cable subscribers (most of which resided east of the [[Mississippi River]]) lost access to WWOR's programming as a consequence.<ref name="variety-wwor">{{cite web|title=Animal Eats WWOR|url=https://variety.com/1996/scene/vpage/animal-eats-wwor-1117436170/|author=John Dempsey|periodical=Variety|publisher=Cahners Business Information|date=December 30, 1996|access-date=April 30, 2019}}</ref><ref name="b&c-wwor">{{cite web|title=N.Y.'s WWOR loses super status; satellite distributor discontinues service contract with television station|url=http://www.highbeam.com/doc/1G1-19009914.html|author=Jim McConville|periodical=Broadcasting & Cable|publisher=Cahners Business Information|via=HighBeam Research|date=January 6, 1997|access-date=February 24, 2011|archive-url=https://web.archive.org/web/20121105151525/http://www.highbeam.com/doc/1G1-19009914.html|url-status=dead|archive-date=November 5, 2012}}</ref><ref>{{cite web|title=Discovery dogs WWOR; Animal Planet gets leg up on Open Slots |url=http://www.highbeam.com/doc/1G1-19193323.html|author=Charles Paikert|periodical=Multichannel News|publisher=Cahners Business Information|via=HighBeam Research|date=January 6, 1997|access-date=February 24, 2011|archive-url=https://web.archive.org/web/20121105151531/http://www.highbeam.com/doc/1G1-19193323.html|url-status=dead|archive-date=November 5, 2012}}</ref> Amid outcry from satellite dish owners, less than one week after the EMI Service feed was discontinued, the National Programming Service, LLC (NPS) subsidiary of carrier firm [[All American Direct]] uplinked the station's New York-area broadcast feed on a separate satellite transponder for exclusive distribution by satellite providers; since syndication exclusivity rules did not apply to home dish providers at the time, the NPS-delivered feed featured all syndicated and UPN network programs that could be seen by viewers in the New York City market. (Because of this, select cable providers picked up the NPS feed to serve as a default UPN programming source in markets where no local UPN affiliate existed, either due to the lack of a standalone fifth or sixth secular commercial station for an exclusive affiliation – particularly through the loss of affiliate clearances to The WB, as was the case in certain markets affected by that network's 1997 agreement with the [[Sinclair Broadcast Group]] – or the lack of a secondary clearance with an existing commercial network station.) The NPS-delivered feed was discontinued in 1999 to repurpose the transponder to distribute the national feed of Pax TV (now [[Ion Television]]), though [[Dish Network]] continues to distribute WWOR nationwide {{as of|2019|lc=y}}, primarily in areas that do not have a local MyNetworkTV affiliate.

[[TBS (TV network)|TBS]], the national version of WTBS, evolved into a hybrid superstation on January 1, 1998. Upon undertaking the operational conventions of a traditional basic cable service, the national channel—which, following a series of name alterations between 1987 and 1996, was known at the time as TBS Superstation—began to collect subscriber fees and, as it was now effectively exempt from the 1976 Copyright Act's signal modification restrictions, began offering systems the ability to lease advertising time to participating providers for the sale and [[local insertion|insertion]] of local commercials. The TBS cable channel, however, retained the WTBS signal as its originating feed and continued to simulcast almost all of the programming seen in the Atlanta market (except for Atlanta-targeted advertisements, and customary weekend morning blocks of public affairs and syndicated educational programs intended to fulfill FCC public service and [[Children's Television Act]] requirements that were shown exclusively on WTBS).<ref>{{cite magazine|title=TBS to go basic, Braves or no|author=Steve McClellan|periodical=Broadcasting & Cable|publisher=Cahners Business Information|page=11|date=April 21, 1997}}</ref><ref>{{cite magazine|title=Counting down to the new TBS|author=Donna Petrozzello|periodical=Broadcasting & Cable|publisher=Cahners Business Information|pages=100–101|date=December 8, 1997}}</ref> As a byproduct of a [[Major League Baseball on TBS|national broadcast deal]] reached between Turner/Time Warner and Major League Baseball that granted TBS rights to carry regular season and postseason games involving various MLB teams (ending its team-specific focus on games involving the Atlanta Braves that traced before it achieved national distribution), TBS eventually gave up its superstation status altogether on October 1, 2007, when the TBS cable channel and WTBS formally separated their programming schedules and branding. The former Atlanta broadcast feed concurrently changed its call letters to WPCH-TV (rebranding as "Peachtree TV") and began targeting its programming exclusively toward its home market, limiting its distribution within North America (outside the Atlanta market) to Canadian television providers that were already receiving the station prior to the TBS split.<ref>{{cite news|title=WTBS to become Peachtree TV|url=http://atlanta.bizjournals.com/atlanta/stories/2007/06/25/daily32.html?surround=lfn|newspaper=Atlanta Business Chronicle|publisher=[[American City Business Journals]]|date=June 27, 2007|access-date=January 11, 2008}}</ref><ref>{{cite press release|title=Turner Pressroom<!-- Bot generated title -->|url=http://www.turnerinfo.com/newsitem.aspx?P=TBS&CID01=aa8051cc-f1f4-4b7f-ad1d-ce2809be3b6f|website=[[Turner Broadcasting System]]|archive-url=https://web.archive.org/web/20071012050942/http://www.turnerinfo.com/newsitem.aspx?P=TBS&CID01=aa8051cc-f1f4-4b7f-ad1d-ce2809be3b6f|archive-date=October 12, 2007}}</ref>

The separation of TBS from its founding Atlanta parent left the WGN national feed – which became known as Superstation WGN in November 2002 and then as [[WGN America]] in May 2008 – as the last remaining superstation to be transmitted nationwide through all multichannel television distribution methods, whereas the other six remaining superstations are available only through satellite television. Into the 2000s, WGN America increasingly relied less on WGN-TV program simulcasts as fewer syndicated programs seen on the Chicago feed were able to be given national "full-signal" clearances, opting to plug holes in the schedule with more "SyndEx-proof" syndicated programs. (Programming shared between the national and local WGN feeds in later years consisted of a limited number of syndicated programs and selected feature films; most Chicago Cubs and White Sox baseball and select Bulls basketball games; select local news and public affairs programs; and certain local and syndicated [[television specials|specials]].) The channel also chose not to carry newscasts and Chicago-originated lifestyle and entertainment programs that WGN-TV added to its schedule as the station began to better emphasize news and other locally produced content starting in 2008. Following the Tribune Company's emergence from [[Chapter 11, Title 11, United States Code|Chapter 11 bankruptcy protection]] amid a debt-laden 2007 [[leveraged buyout]] by real estate investor [[Sam Zell]] and subsequent takeover by three [[private equity firm]]s ([[Oaktree Capital Management]], [[JPMorgan Chase]] and [[Angelo, Gordon & Co.]]), Tribune unveiled plans to turn WGN America into a conventional basic cable network incorporating original programming content, to increase the channel's visibility and stave off potential defections from television providers because of the expense of paying increasing copyright fees to transmit programs now readily available elsewhere. (Through this conversion, WGN America began phasing out all local news and sports programming simulcast with the Chicago signal, concluding with the removal of its morning and midday newscasts from WGN America's lineup on December 15, 2014.<ref>{{cite web|title=WGN news loses national platform|url=http://www.robertfeder.com/2014/02/05/wgn-9-p-m-news-loses-national-platform|author=Robert Feder|newspaper=Chicago Tribune|publisher=Tribune Publishing|date=February 5, 2014|access-date=February 7, 2014}}</ref><ref name=ccb-wgnanosports>{{cite news|title=WGN America to drop Chicago sports|url=http://www.chicagobusiness.com/article/20140530/NEWS01/140539978/wgn-america-to-drop-chicago-sports|author=Lynne Marek|newspaper=[[Crain's Chicago Business]]|publisher=[[Crain Communications]]|date=May 30, 2014|access-date=June 27, 2014}}</ref>) WGN's superstation status ended (in the United States) on December 16, 2014, when all remaining simulcasts of the Chicago station's local news, public affairs and sports programming were removed from its schedule and the first carriage agreements that shifted WGN America from limited to expanded basic tiers (involving [[Comcast Cable|Comcast Xfinity]] systems in Chicago and four other major markets) went into effect.<ref name="feder-wgnacomcast">{{cite news|title=WGN America comes home to Chicago|url=http://www.robertfeder.com/2014/12/15/wgn-america-comes-home-to-chicago/|author=[[Robert Feder]]|newspaper=Chicago Tribune|publisher=Tribune Publishing|date=December 15, 2014|access-date=January 11, 2015}}</ref><ref name="b&c-wgnacomcast">{{cite news|title=WGN America Converts to Cable in Five Markets|url=http://www.broadcastingcable.com/news/programming/wgn-america-converts-cable-five-markets/136444|author=Kent Gibbons|periodical=Broadcasting & Cable|publisher=NewBay Media|date=December 16, 2014|access-date=January 11, 2015}}</ref> WGN-TV would eventually be made available throughout the United States once again in the spring of 2015, when antenna manufacturer [[Channel Master]] included the Chicago-area feed among the initial offerings on its short-lived [[Internet television|over-the-top streaming service]] LinearTV.<ref name="b&c-channelmaster">{{cite web|title=CES: Channel Master DVR to Pipe in Linear OTT|url=http://www.broadcastingcable.com/news/technology/ces-channel-master-dvr-pipe-linear-ott/136765|author=Jeff Baumgartner|periodical=Broadcasting & Cable|publisher=NewBay Media|date=January 6, 2015|access-date=September 9, 2015}}</ref>

The five remaining "true" superstations—WPIX, KTLA, KWGN-TV, WWOR-TV and WSBK-TV—are carried on some rural cable providers and via satellite through Dish Network and C-Band systems. Since the 1988 syndication exclusivity rules were implemented, [[WKAQ-TV]] (channel 2) in [[San Juan, Puerto Rico|San Juan]] and [[WAPA-TV]] (channel 4) in [[Guaynabo|Guaynabo, Puerto Rico]] have been the only American television stations to achieve superstation status, although neither fits the legal criteria of a superstation as defined by the FCC. WKAQ's signal became available in the mainland United States in 2001, when Telemundo Group converted its Telemundo Internacional cable channel—which began as a [[United States cable news|cable news channel]] under the name Telenoticias in 1994—into a national feed of the station, branded as [[Telemundo Puerto Rico (TV channel)|Telemundo Puerto Rico]]; the feed is available in the contiguous United States through select cable providers and via satellite on Dish Network and [[DirecTV]]. [[LIN Media|LIN Television Corp.]] began distributing a direct-to-satellite national feed of WAPA-TV, [[WAPA America]], on September 1, 2004, through DirecTV's Para Todos Spanish-language tier; WAPA America is also available through select cable providers and on Dish Network.<ref>{{cite press release|title=WAPA-America Debuts on DIRECTV PARA TODOS Programming Service|url=https://www.businesswire.com/news/home/20040823005215/en/WAPA-America-Debuts-DIRECTV-PARA-TODOS-Programming-Service|website=[[DirecTV|DirecTV, Inc.]]|publisher=The DirecTV Group Inc.|via=[[Business Wire]]|date=August 23, 2004|access-date=April 30, 2019}}</ref><ref>{{cite press release|title=Leading Puerto Rican Channel, WAPA America, Launches on DISH Network|url=https://www.prnewswire.com/news-releases/leading-puerto-rican-channel-wapa-america-launches-on-dish-network-129525678.html|website=WAPA America|via=Business Wire|date=September 9, 2011|access-date=April 30, 2019}}</ref> (Unlike the five superstations licensed within the U.S. mainland, WAPA's programming is generally "SyndEx-proof" as its schedule consists of domestically produced programs and acquired programming not widely available on broadcasters elsewhere within the Continental United States.) Since its inception in 1994, Dish Network has offered an [[a la carte cable television|a la carte]] tier of all five aforementioned mainland superstations to subscribers outside of the stations' respective home markets. The tier continued to be sold for many years following the 1999 passage of the Satellite Home Viewer Improvement Act, despite concerns expressed by representatives for former Dish parent [[EchoStar]] that prevalent program blackouts caused by requests from local broadcast licensees made under SHVIA syndication exclusivity and sports blackout provisions could force it to drop the five mainland superstations from its lineup. Indeed, such requests have led Dish Network to stop offering one or more of the stations in some markets in recent years, culminating in Dish ceasing all future sales of the superstation tier on September 19, 2013. (A grandfathering waiver exists for subscribers who purchased the tier prior to the cut-off date, allowing them to continue receiving the superstation package barring they ever cancel their subscription to the tier or to Dish Network.)<ref>{{cite web|title=Dish to stop superstation subscriptions|url=https://freetvblog.com/2013/09/10/dish-to-stop-superstation-subscriptions/|website=Free TV Blog|date=September 10, 2013|access-date=April 30, 2019}}</ref>
