Commercial broadcasting

Practice of airing radio and television advertisements for profit

Commercial broadcasting is the broadcasting of television programs and radio programming by privately owned corporate media, as opposed to state sponsorship, for example. It was the United States' first model of radio during the 1920s, in contrast with the public television model during the 1930s, 1940s, and 1950s, which prevailed worldwide, except in the United States, Mexico, and Brazil, until the 1980s.
