American Telephone and Telegraph, Inc.
     
         (AT&T) One of the
        largest US telecommunications providers.  Also noted for being
        the birthplace of the {Unix} {operating system} and the {C}
        and {C++} programming languages.
     
        AT&T was incorporated in 1885, but traces its lineage to
        Alexander Graham Bell and his invention of the telephone in
        1876.  As parent company of the former {Bell System}, AT&T's
        primary mission was to provide telephone service to virtually
        everyone in the United States.  In its first 50 years, AT&T
        established subsidiaries and allied companies in more than a
        dozen other countries.  It sold these interests in 1925 and
        focused on achieving its mission in the United States.  It
        did, however, continue to provide international long distance
        service.
     
        The Bell System was dissolved at the end of 1983 with AT&T's
        divestiture of the Bell telephone companies.
     
        AT&T split into three parts in 1996, one of which is {Lucent
        Tecnologies}, the former systems and equipment portion of AT&T
        (including Bell Laboratories).
