PBS has [[Corporate spin-off|spun off]] a number of [[television network]]s, often in partnership with other media companies. [[PBS YOU]], a distance education and how-to service operated between 2000 and 2006, and was largely succeeded by [[Create (TV network)|Create]] (a similarly formatted network owned by American Public Television). The 24-hour PBS Kids Channel has had two iterations in the age of [[digital television]]; one which existed between 1999 and 2005 (being superseded by PBS Kids Sprout), and the current version which was launched in 2017. [[World (TV network)|World]] began operations in 2007 as a service operated by PBS but is now managed by American Public Television.

PBS has also restructured its satellite feed system, simplifying [[PBS-HD|HD02 (PBS West)]] into a timeshift feed for the [[Pacific Time Zone]], rather than a high-definition complement to its formerly primary SD feed. [[PBS Kids Go!]] was proposed as a replacement broadcast network for the original 1999–2005 version of the PBS Kids Channel; however, plans to launch the network were folded in 2006. Programming from the PBS Satellite Service has also been carried by certain member stations or regional member networks to fill their overnight schedules (particularly those that have transitioned to a 24-hour schedule since the late 1990s), in lieu of providing programming sourced from outside public television distributors or repeats of local programming (program promotions shown on the satellite feed advertise upcoming programs as being aired on PBS during the timeslot card normally used as a placeholder for member outlets to insert local airtime information).

Some or all of these services are available on a digital cable tier of many cable providers, on a [[FTA receiver|free-to-air (FTA) satellite receiver]] receiving from [[PBS Satellite Service]], as well as via subscription-based [[direct broadcast satellite]] providers. With the exception of Sprout, some of these services, including those from PBS member stations and networks, have not made contracts with Internet-distributed [[over-the-top content|over-the-top]] [[multichannel video programming distributor|MVPD]] services such as [[Sling TV]] and the now defunct [[PlayStation Vue]]. With the transition to over-the-air [[digital television]] broadcasts, many of the services are also often now available as standard-definition [[Multicast#Television|multicast]] channels on the digital signals of some member stations, while HD02 (PBS West) serves as a secondary HD feed. With the absence of [[advertising]], network identification on these PBS networks was limited to utilization at the end of the program, which includes the standard series of [[Commercial bumper|bumpers]] from the "Be More" campaign.

===Independent networks===
While not operated or controlled by PBS proper, additional public broadcasting networks are available and carried by PBS member stations. The following three are also distributed by PBS via satellite.

From 2002 to 2011, [[Buffalo, New York]] member station [[WNED-TV]] operated [[ThinkBright|ThinkBright TV]], a service that was carried on several stations in upstate [[New York (state)|New York]]. Several state networks also offer a [[Public affairs (broadcasting)|public affairs]] subchannel network offering full-time coverage of state government events and legislative/judicial proceedings in the same vein as [[C-SPAN]]'s coverage of the federal government. Many PBS stations also carried MHz Worldview from the [[MHz Networks]] until 2020 when MHz Networks announced its discontinuation of the network on March 1, 2020. Since then, many stations has switched to World Channel as well as [[First Nations Experience]].

A separate but related concept is the state network, where a group of stations across a state simulcast a single programming schedule from a central facility, which may include specialty subchannels unique to that broadcaster.
