The Bell System was a system of telecommunication companies, led by the Bell Telephone Company and later by the American Telephone and Telegraph Company (AT&T), that dominated the telephone services industry in North America for over one hundred years from its creation in 1877 until its antitrust breakup in 1983.
Bell System, a former American telephone system, governed by American Telephone & Telegraph Company (now AT&T Corporation; q.v.) and including Western Electric Company (q.v.), the system’s manufacturer; Bell Laboratories (q.v.), the research and development facility; and other departments
The breakup of the Bell System was mandated on January 8, 1982, by a consent decree providing that AT&T Corporation would, as had been initially proposed by AT&T, relinquish control of the Bell Operating Companies, which had provided local telephone service in the United States.
The Bell Telephone System was once called "Ma Bell" or "the telephone company." The system consisted of 24 Bell operating companies that became the "Baby Bells," comprising a huge network of telecommunications equipment.
