Which entity is responsible for regulating interstate and foreign communications?

The Federal Communications Commission (FCC) is the entity responsible for regulating interstate and foreign communications. This regulatory body oversees various aspects of telecommunications, including radio, television, wire, satellite, and cable communications, ensuring that these services operate under federal laws and regulations.

The FCC's role encompasses a broad range of activities, such as licensing broadcasters, managing the electromagnetic spectrum, and enforcing communication regulations to promote competition and protect consumers. By establishing rules and guidelines, the FCC helps to foster an environment in which reliable communication services can thrive, both domestically and in interactions with international entities.

The Federal Trade Commission, while important in regulating unfair or deceptive practices in commerce, does not have the purview over communication systems. The Department of Justice focuses on enforcing federal laws and ensuring justice, particularly in legal matters related to anti-trust and civil rights. Meanwhile, the Department of Commerce is concerned with promoting economic growth and job creation, rather than specifically regulating communication services. Thus, the FCC is the appropriate agency for this regulatory role.
