Overview
PBS was founded on October 5, 1970, at which time it took over many of the functions of its predecessor, National Educational Television (NET), which later merged with station WNDT, Newark, New Jersey, to form WNET. In 1973, it merged with Educational Television Stations.
Unlike the model of America's commercial broadcasting television networks, in which affiliates give up portions of their local advertising airtime in exchange for network programming, PBS member stations pay fees for the shows acquired and distributed by the national organization.
This relationship means that PBS member stations have greater latitude in local scheduling than their commercial broadcasting counterparts. Scheduling of PBS-distributed series may vary greatly from market to market. This can be a source of tension as stations seek to preserve their localism, and PBS strives to market a consistent national line-up. However, PBS has a policy of "common carriage" requiring most stations to clear the national prime-time programs on a common broadcast programming schedule, so that they can be more effectively marketed on a national basis.
Unlike its radio counterpart, National Public Radio, PBS has no central program production arm or news department. All of the programming carried by PBS, whether news, documentary, or entertainment, is created by (or in most cases produced under contract with) other parties, such as individual member stations. WGBH in Boston is one of the largest producers of educational television programming, including American Experience, Masterpiece Theater, Nova, Antiques Roadshow and Frontline, as well as many other children's and lifestyle shows. News programs are produced by WETA-TV (PBS Newshour) in Washington, D.C., WNET in New York and WPBT in Miami. The Charlie Rose interview show, Secrets of the Dead, NOW on PBS, Nature, and Cyberchase come from or through WNET in New York. Once a program is offered to, and accepted by, PBS for distribution, PBS (and not the member station that supplied the program) retains exclusive rights for rebroadcasts during the period for which such rights were granted; the suppliers do maintain the right to sell the program in non-broadcast media such as DVDs, books, and sometimes PBS licensed merchandise (but sometimes grant such ancillary rights as well to PBS).
PBS stations are commonly operated by non-profit organizations, state agencies, local authorities (e.g., municipal boards of education), or universities in their city of license. In some U.S. states, PBS stations throughout the entire state may be organized into a single regional "subnetwork" called a state network (e.g., Alabama Public Television). Unlike public broadcasters in most other countries, PBS does not own any of the stations that broadcast its programming (i.e., there are no PBS owned-and-operated stations (O&O) anywhere in the country). This is partly due to the origins of the PBS stations themselves, and partly due to historical broadcast license issues.
In the modern broadcast marketplace, this organizational structure is considered outmoded by some media critics. A common restructuring proposal is to reorganize the network so that each state would have one PBS member which would broadcast state-wide. However, this proposal is controversial, as it would reduce local community input into PBS programming, especially considering how PBS stations are significantly more community-oriented, according to the argument, than their commercial broadcasting counterparts.
In 1994, The Chronicle of Philanthropy, an industry publication, released the results of the largest study of charitable and non-profit organization popularity and credibility. The study showed that PBS was ranked as the 11th "most popular charity/non-profit in America" from over 100 charities researched, with 38.2% of Americans over the age of 12 choosing "love" and "like a lot" for PBS.
In December 2009, PBS signed up for the Nielsen ratings audience measurement reports for the first time.
