Federal Communications Commission

Federal Communications Commission (FCC), independent agency of the United States government created in 1934, with jurisdiction over communications in the 50 states, Guam, Puerto Rico, and the Virgin Islands. The function of the commission is to regulate interstate and foreign radio, television, wire, and cable communications; to provide for orderly development and operation of broadcasting services; to provide for rapid, efficient nationwide and worldwide telegraph and telephone service; to promote the safety of life and property through the use of wire and radio communications; and to employ communications facilities for strengthening national defense.

In the field of radio, the FCC regulates amplitude modulation (AM) and frequency modulation (FM) broadcasting and other kinds of radio services. It issues construction permits and licenses for all nongovernmental radio stations. It also assigns frequencies, operating power, and call signs; inspects transmitting equipment, and regulates the use of such equipment. Television broadcasting is regulated by the FCC in the same manner. The commission also regulates the use of cable channels and the quality of service delivered by cable television.

In common-carrier operations, which include telephone, telegraph, radio, and satellite communications, the FCC issues regulations and supervises service. The FCC is responsible for domestic administration of the telecommunications provisions of treaties and international agreements, and licenses radio and cable circuits from the United States to foreign points. The Emergency Broadcast System, which alerts and instructs the public in the event of enemy attack, is supervised by the FCC; the system is regularly used for broadcasting weather warnings and may also be used in local emergencies.

The FCC is administered by five commissioners appointed by the president, with approval of the Senate, to five-year terms.
