AT&T Inc.
A provider of wireless phone and internet service, AT&T runs one of the largest mobile networks in the US, selling broadband under brands like Cricket, AT&T PREPAID, and AT&T Internet Air, plus a dedicated network for first responders called FirstNet. It traces its roots to Alexander Graham Bell's Bell Telephone Company, founded in 1877, and was incorporated in 1885 as the American Telephone and Telegraph Company to build the nation's first long-distance network — its name is simply an abbreviation of that original title.
