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. It was the United States' first model of radio (and later television) during the 1920s, in contrast with the
public television model in
Europe during the 1930s, 1940s and 1950s which prevailed worldwide (except in the United States) until the 1980s.
