The Canadian Broadcasting Corporation (French: Société Radio-Canada), officially branded as CBC/Radio-Canada, is a Canadian crown corporation (state sponsored) that serves as the national public radio and televisionbroadcaster. The English- and French-language services units of the corporation are commonly known as CBC and Ici Radio-Canada respectively, and both short-form names are also commonly used in the applicable language to refer to the corporation as a whole.
Although some local stations in Canada predate CBC's founding, CBC is the oldest existing broadcasting network in Canada, first established in its present form on November 2, 1936. Radio services include CBC Radio One, CBC Radio 2, Ici Radio-Canada Première, Espace musique and the international radio service Radio Canada International. Television operations include CBC Television, Ici Radio-Canada Télé, CBC News Network, Ici RDI, Ici Explora, Ici ARTV(part ownership), and documentary. The CBC operates services for the Canadian Arctic under the names CBC Northand Radio-Canada Nord. The CBC also operates digital services including CBC.ca / Ici.Radio-Canada.ca, CBC Radio 3,CBC Music / espace.mu and Ici.TOU.TV, and owns 20.2% of satellite radio broadcaster Sirius XM Canada, which carries several CBC-produced audio channels.
CBC/Radio-Canada offers programming in English, French and eight Aboriginal languages on its domestic radio service, and in five languages on its web-based international radio service, Radio Canada International (RCI). However, budget cuts in the early 2010s have contributed to the corporation reducing its service via the airwaves, discontinuing RCI's shortwave broadcasts as well as terrestrial television broadcasts in all communities served by network-ownedrebroadcast transmitters, including communities not subject to Canada's over-the-air digital television transition.
The financial structure and the nature of the CBC differs from other national broadcasters, such as the British broadcaster BBC, as the CBC employs commercial advertising to supplement its federal funding on its television broadcasts. The radio service employed commercials from its inception to 1974. Since then, its radio service, like the BBC, has been commercial-free. However, since the fall of 2013, CBC's FM Radio Networks Radio 2 and Espace Musique have introduced limited advertising amounting to 4 minutes an hour.
