History
changeThe company was formed in 1885 as American Telephone and Telegraph. In 1900 the company introduced the Bell System. The company quickly gained a monopoly on the phone industry. The government was going to investigate, but World War 2 started, so they were distracted. In 1964 the name of American Telephone and Telegraph was changed to AT&T Corporation.
In 1983 the company was forced to spin-off the Bell System into seven new companies. One of the new companies was SBC Communications. SBC united a majority of the companies until 2005, when they bought AT&T itself (they would take the name of the company.) Another company (Bell Atlantic) would form Verizon.
