Which organization in the U.S. is responsible for regulating communication?

The Federal Communications Commission (FCC) is the correct answer because it is the primary regulatory body in the United States responsible for overseeing and managing interstate and international communications by radio, television, wire, satellite, and cable. The FCC has a wide range of responsibilities, including issuing licenses to broadcasters, regulating content to ensure it meets certain standards, and managing the electromagnetic spectrum to facilitate efficient use of communication technologies.

Understanding the roles of other organizations helps to clarify why they are not the appropriate answer. The American Broadcasting Company (ABC) is a television network and does not regulate communication; rather, it is a provider of content. National Public Radio (NPR) is a non-profit media organization that delivers news and cultural programming but does not have regulatory authority over communication practices. The Federal Trade Commission (FTC) focuses on consumer protection and antitrust issues rather than communication regulation. Each of these organizations plays an important role in the media landscape, but regulatory functions are specifically the domain of the FCC.
