The Public Broadcasting Service (PBS) is an American public broadcaster and non-commercial, free-to-air television network based in Arlington, Virginia. PBS is a publicly funded nonprofit organization and the most prominent provider of educational programming to public television stations in the United States, distributing shows such as Frontline, Nova, PBS NewsHour, Sesame Street, and This Old House.PBS is funded by a combination of member station dues, the Corporation for Public Broadcasting, pledge drives, and donations from both private foundations and individual citizens. All proposed funding for programming is subject to a set of standards to ensure the program is free of influence from the funding source. PBS has over 350 member television stations, many owned by educational institutions, nonprofit groups both independent or affiliated with one particular local public school district or collegiate educational institution, or entities owned by or related to state government.

National Educational Television (NET) was an American educational broadcast television network owned by the Ford Foundation and later co-owned by the Corporation for Public Broadcasting. It operated from May 16, 1954 to October 4, 1970, and was succeeded by the Public Broadcasting Service (PBS), which has memberships with many television stations that were formerly part of NET.

The Council on Library and Information Resources (CLIR) provided funds for cataloging the NET collection, and as part of an on-going preservation effort with the Library of Congress, over 10,000 digitized television programs from the non-commercial TV stations and producers spanning 1952 to 1972 have been contributed to the American Archive of Public Broadcasting.
