Radio became increasingly attractive as an advertising medium with the coming of network operation. A coast-to-coast hookup was tentatively effected early in 1924, and expansion of both audience and transmission facilities continued rapidly. By 1927 there were two major networks, and the number of stations had so increased that interference became a serious problem. Legislation (see Federal Communications Commission Federal Communications Commission (FCC), independent executive agency of the U.S. government established in 1934 to regulate interstate and foreign communications in the public interest. .....

By 2003, 4,804 commercial radio stations were operating in the original AM (amplitude modulation) broadcast band. Commercial broadcasting on the FM (frequency modulation) band began in 1941. The number of FM stations passed the number of AM in 1983; in 1998 there were 6,179 commercial FM stations on the air, and 2,400 noncommercial stations. Experiments in broadcasting television began in the 1920s but were interrupted by World War II. In 1996 there were 1,340 commercial television stations on the air, and 600 noncommercial stations. There were also more than 2,000 low-power television stations. The Corporation for Public Broadcasting was established in 1968 as a not-for-profit, nongovernmental agency to finance the growth of noncommercial radio and television; by 2003 the network served more than 200 television and nearly 800 radio stations. New and competing technologies have had a tremendous impact on broadcasting and the ways in which people use it. With the availability of small, high-quality portable and automotive receivers, it has been estimated that less than half of all radio listening takes place in the home.

The new cable channels, most of them highly specialized in the programming they offer, coupled with the wide availability of videocassettes and DVDs, have reduced the influence of the broadcast networks. Television signals are also now transmitted from satellites direct to household satellite dishes. See radio radio, transmission or reception of electromagnetic radiation in the radio frequency range.

After Guglielmo Marconi's discovery of wireless broadcasting in 1901, radio broadcasting was undertaken by amateurs. The first U.S. commercial radio station, KDKA of Pittsburgh, began operation in 1920. The number of stations increased rapidly, as did the formation of national radio networks. To avoid radio monopolies, Congress passed the Radio Act of 1927, which created the Federal Communications Commission to oversee broadcast operations. In the 1930s and '40s, the “golden age of radio,” innovations in broadcast techniques and programming made radio the most popular entertainment medium. Television broadcasting began in Germany and Britain in the 1930s. After World War II, the U.S. took the lead, and television stations soon overshadowed radio networks. Color television broadcasts began in 1954 and became widespread in the 1960s. By the 1980s, satellite transmission of live television further expanded the field of broadcasting.
