Southern Bell Telephone and Telegraph Company was once the regional Bell Operating Company serving the states of Georgia, Florida, North Carolina, and South Carolina prior to the breakup of AT&T. It also covered the states of Alabama, Kentucky, Louisiana, Mississippi, and Tennessee until 1968 when those were split off to form South Central Bell. The company was originally known as the Atlanta Telephonic Exchange, having been created to service citizens of Atlanta in 1879, before it was renamed in 1882.
