The history of AT & T is , in many ways , the history of the entire telephone system in the United States , thanks to its precursor the Bell Telephone company . Established by Alexander Graham Bell ’ s father in law , the company evolved into the American Telephone and Telegraph Company , and controlled the Bell System of telephone services across the nation . Accused of being a monopoly , it was broken up in 1983 by the US government , creating many of AT & T ’ s current competitors . The current company was itself reformed out of Southwestern Bell , one of those spun off companies .
