"The Federal Communications Commission (FCC) is an independent federal agency with its five members appointed by the President, subject to confirmation by the Senate. It was established by the Communications Act of 1934 (1934 Act) and is charged with regulating interstate and international communications by radio, television, wire, satellite, and cable. The mission of the FCC is to ensure that the American people have available--at reasonable cost and without discrimination--rapid, efficient, nation- and world-wide communication services, whether by radio, television, wire, satellite, or cable."
