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. PBS has nearly 350 member stations around the United States. History PBS was established on November 3, 1969, by Hartford N. Gunn Jr. (president of WGBH), John Macy (president of CPB), James Day (last president of National Educational Television), and Kenneth A. Christiansen (chairman of the department of broadcasting at the University of Florida). It began operations on October 5, 1970, taking over many of the functions of its predecessor, National Educational Television (NET), which later merged with Newark, New Jersey station WNDT to form WNET. In 1973, it merged with Educational Television Stations. Immediately after public disclosure of the Watergate scandal, on May 17, 1973, the United States Senate Watergate Committee commenced proceedings; PBS broadcast the proceedings nationwide, with Robert MacNeil and Jim Lehrer as commentators. Although all of the Big Three TV Networks ran coverage of the hearings, PBS re-broadcast them on prime time. For seven months, nightly "gavel-to-gavel" broadcasts drew great public interest, and raised the profile of the fledgling PBS network. In 1991, the Corporation for Public Broadcasting resumed funding for most PBS shows that debuted prior to 1977, with the exceptions of Washington Week in Review and Wall Street Week (CPB resumed funding of Washington Week in 1997). In 1994, The Chronicle of Philanthropy released the results of the largest study on the popularity and credibility of charitable and non-profit organizations. PBS ranked as the 11th "most popular charity/non-profit in America" from over 100 charities researched in the study conducted by the industry publication, with 38.2% of Americans over the age
