Explanation:

The Federal Communications Commission (FCC) is an independent agency of the United States government that regulates communications by radio, television, wire, satellite, and cable across the United State

The FCC is responsible for regulating  all  the  interstate communications, such as wire, satellite and cable, and international communications which either originate or terminates in the United States.The  Radio and television broadcasters must obtain a license from the government because, according to American law, the public owns the airwaves. The Federal Communications Commission (FCC) issues these licenses and is in charge of regulating the airwaves
