Commercial broadcasting

Commercial broadcasting (also called private 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 (and later television) 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.
