Mail The legal monopoly of the government-owned United States Postal Service has narrowed during the 20th and 21st centuries due to competition from companies such as UPS & FedEx, although still delivers the vast majority of US mail. Telephone In 1890, 1 percent of U.S. households owned at least one telephone while a majority did by 1946 and 75 percent did by 1957. 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). Landlines Telephones - main lines in use: 141 million (2009) Most of the American telephone system was formerly operated by a single monopoly, AT&T, which was divided in 1984 into a long-distance telephone company and seven regional "Baby Bells". Landline telephone service continues to be divided between incumbent local exchange carriers and several competing long-distance companies. 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 providers have upgraded 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. Cellular/Wireless communication Telephones - mobile cellular: 286 million (2009) Most states have several competing cellular phone networks. The major cellphone companies in the U.S. are Verizon Wireless, AT&T Mobility, and T-Mobile US.
