State channel

Public broadcasting includes radio, television and other electronic media outlets whose primary mission is public service. In much of the world, funding comes from the government, especially via annual fees charged on receivers. In the United States, public broadcasters may receive some funding from both federal and state sources, but generally most financial support comes from underwriting by foundations and businesses ranging from small shops to corporations, along with audience contributions via pledge drives. The great majority are operated as private not-for-profit corporations.

Public broadcasting may be nationally or locally operated, depending on the country and the station. In some countries, public broadcasting is run by a single organization. Other countries have multiple public broadcasting organizations operating regionally or in different languages. Historically, public broadcasting was once the dominant or only form of broadcasting in many countries (with the notable exception of the United States). Commercial broadcasting now also exists in most of these countries; the number of countries with only public broadcasting declined substantially during the latter part of the 20th century.

The primary mission of public broadcasting that of public service, speaking to and engaging as a citizen. The British model has been widely accepted as a universal definition. The model embodies the following principles:

While application of certain principles may be straightforward, as in the case of accessibility, some of the principles may be poorly defined or difficult to implement. In the context of a shifting national identity, the role of public broadcasting may be unclear. Likewise, the subjective nature of good programming may raise the question of individual or public taste.

Within public broadcasting there are two different views regarding commercial activity. One is that public broadcasting is incompatible with commercial objectives. The other is that public broadcasting can and should compete in the marketplace with commercial broadcasters. This dichotomy is highlighted by the public service aspects of traditional commercial broadcasters.

Public broadcasters in each jurisdiction may or may not be synonymous with government controlled broadcasters. In some countries like the UK public broadcasters are not sanctioned by government departments and have independent means of funding, and thus enjoy editorial independence.

Public broadcasters may receive their funding from an obligatory television licence fee, individual contributions, government funding or commercial sources. Public broadcasters do not rely on advertising to the same degree as commercial broadcasters, or at all; this allows public broadcasters to transmit programmes that are not commercially viable to the mass market, such as public affairs shows, radio and television documentaries, and educational programmes.
