The primary regulator of communications in the United States is the Federal Communications Commission. It closely regulates all of the industries mentioned below with the exception of the Internet service provider industry.

History

Press

Newspapers declined in their influence and penetration into American households in the late 20th century. The closest thing to a national paper the U.S. has is USA Today. Other influential dailies include the New York Times, the Washington Post and the Wall Street Journal which are sold in most U.S. cities. The Times has a moderate-left stance, while the Journal is moderate-right and is strongly pro-business.

The largest newspapers (by circulation) in the United States are USA Today, the Wall Street Journal, the New York Times and the Los Angeles Times.

Mail

Mail in the United States trends towards competition. The legal monopoly of the United States Postal Service (which is in governmental ownership) narrowed during the 20th century.

Landline telephony

Local calls

Telephones - main lines in use: 268 million (2003)

Telephones - mobile cellular: 257 million (Dec 2007)

Telephone system:
General assessment: A large, technologically advanced, multipurpose communications system.
Domestic: A large system of fiber-optic cable, microwave radio relay, coaxial cable, and domestic satellites carries every form of telephone traffic; a rapidly growing cellular system carries mobile telephone traffic throughout the country.
International: Country code - 1; 24 ocean cable systems in use; satellite earth stations - 61 Intelsat (45 Atlantic Ocean and 16 Pacific Ocean), 5 Intersputnik (Atlantic Ocean region), and 4 Inmarsat (Pacific and Atlantic Ocean regions) (2000).

• Note: Most of the American telephone system was formerly operated by a single monopoly, AT&T, which was split up in 1984 into a long distance telephone company and several local "Baby Bells."
• Landline telephone service continues to be divided between incumbent local exchange carriers and several competing long distance companies. Most states have several competing cellular phone networks. As of 2005, some of the Baby Bells are beginning to merge with long-distance phone companies. A small number of consumers are currently experimenting with Voice over Internet Protocol phone service.
• Most local loop service to homes is provided through old-fashioned copper wire, although many of the Baby Bells are beginning to upgrade the so-called "last mile" to fiber optic.
• Early in the 21st century the number of wire lines in use stopped growing and in some markets began to decline^[1].

International calls

Radio

Radio broadcast stations: AM: 4,789; FM commercial stations: 6,231; FM educational stations: 2,672; FM translators & boosters: 3,995; low-power FM stations: 675 (as of December 31, 2005, according to the Federal Communications Commission)

• Most broadcast stations are controlled by large media conglomerates like Clear Channel Communications. There are also many small independent local stations. National Public Radio (NPR) is the public radio network.

Radios: 575 million (1997)

Television

Television broadcast stations: 9,024 (of which 1,750 are full-power TV stations; 592 are class-A TV stations; 4,537 are TV translators; and 2,145 are other low-power TV stations) (as of December 31, 2005, according to the Federal Communications Commission); in addition, there are about 12,000 cable TV systems.

• Most local commercial television stations are owned-and-operated by or affiliated with the large national broadcast networks such as ABC, CBS, Fox, NBC, and The CW. Some television networks are aimed at ethnic minorities, including Spanish language networks Univisión and Telemundo. Public Broadcasting Service (PBS), is the public broadcasting network, with over 300 non-profit affiliated stations across the United States. Besides the large broadcast networks (which are free for anyone with a TV and an antenna), there are also many networks available only with a subscription to cable or satellite television, like CNN.

Televisions: 219 million (1997)

Cellular communication

The five major cellphone companies in the U.S. are AT&T Mobility, Verizon Wireless, Sprint Nextel, T-Mobile and Alltel.

Internet

Internet Service Providers (ISPs): 7,600 (1999 est.)

• Because of aggressive lobbying and the United States' strong libertarian traditions, the Internet service provider industry remains relatively unregulated in comparison to other communications industries.

Country code (Top level domain): US

• For various historical reasons, the .us domain was never widely used outside of a small number of government agencies and school districts. Most companies signed up for top level domains like .com instead.
• NeuStar Inc. now has control over the .us registry and is trying to promote the domain as an option for American-oriented Web sites.
