Final answer:
The International Telecommunication Union (ITU) is the specialized UN agency that regulates international telecommunications, with the Federal Communications Commission (FCC) serving a similar role within the USA.
Step-by-step explanation:
The International Telecommunication Union (ITU) is a specialized agency of the United Nations that regulates international telecommunications. It is responsible for radio and TV frequencies, satellite and telephony specifications, networking infrastructure, and tariffs applied to global communications. Stateside, the Federal Communications Commission (FCC) fulfills a similar role on a national level.
The FCC is an independent agency of the United States government, established by Congressional statute to regulate interstate communications by radio, television, wire, satellite, and cable across all 50 states, the District of Columbia, and U.S. territories.
The FCC works to promote six goals in the areas of broadband, competition, the spectrum, the media, public safety, and homeland security. As technology evolves, the FCC continues to modernize to better supervise instant communication technology including the Internet and digital television.
