The Pacific Bell Telephone Company (Pacific Bell) is a telephone company that provides telephone service in California. The company is owned by AT&T Inc. through AT&T Teleholdings, and, though separate, is now marketed as “AT&T”. The company has been known by a number of names during which its service area has changed. The formal name of the company from the 1910s through the 1984 Bell System divestiture was The Pacific Telephone and Telegraph Company. As of 2002, the name “Pacific Bell” is no longer used in marketing, Pacific Bell is still the holder of record for the infrastructure of cables and fiber through much of California.
