Which agency is responsible for licensing and regulating radio and television stations?

The Federal Communications Commission (FCC) is the agency responsible for licensing and regulating radio and television stations in the United States. It oversees the operation of these stations to ensure compliance with federal laws, promote fair competition, and manage the use of the electromagnetic spectrum. The FCC's role is crucial in maintaining standards related to broadcasting, including issues of public safety, content regulation, and the provision of services to underserved communities.

Other organizations mentioned, such as the Federal Trade Commission (FTC), focus on consumer protection and antitrust issues rather than broadcasting regulation. The National Association of Broadcasters (NAB) serves as a trade association for the broadcasting industry and advocates for its members but does not have regulatory authority. The American Broadcasting Company (ABC) is a television network and does not engage in regulatory functions. Thus, the FCC is uniquely positioned to oversee and grant the necessary licenses for broadcasting entities.
