Radio and Television
Radio news made its appearance in the 1920s. The National Broadcasting Company (NBC) and the Columbia Broadcasting System (CBS) began running sponsored news programs and radio dramas.

News and entertainment programs were also targeted to rural communities.
Television combined the best attributes of radio and pictures and changed media forever. As on the radio, quiz shows and games initially dominated the television airwaves. But when Edward R. Murrow made the move to television in 1951 with his news show See It Now, television journalism gained its foothold. As television programming expanded, more channels were added.
