Where is the headquarters of AT&T? Who founded AT&T?

AT&T, an American multinational telecommunications holding company, is headquartered at Whitacre Tower in Downtown Dallas, Texas. The address of the headquarters is 208 S. Akard St., Dallas, TX 75202.

The history of AT&T dates back to the invention of the telephone. The Bell Telephone Company was established in 1877 by Alexander Graham Bell, who obtained the first US patent for the telephone, and his father-in-law, Gardiner Greene Hubbard.

Bell and Hubbard also established American Telephone and Telegraph Company in 1885, which acquired the Bell Telephone Company and became the primary telephone company in the United States. This company maintained an effective monopoly on local telephone service in the United States until anti-trust regulators split the Bell System by divesting itself of ownership of the Bell Operating Companies in 1982.

AT&T Corporation was eventually purchased by one of its Regional Bell Operating Companies, the former Southwestern Bell Company, in 2005, and the combined company became known as AT&T Inc.
