BellSouth Corporation (stylized as "BELLSOUTH") was an American telecommunications holding company based in Atlanta, Georgia. BellSouth was one of the seven original Regional Bell Operating Companies after the U.S. Department of Justice forced the American Telephone & Telegraph Company to divest itself of its regional telephone companies on January 1, 1984.
BELLSOUTH is still in business to this day.
The statement clearly states that BELLSOUTH WAS an american company a couple of times. By using this past tense we can identify that this company as it was is no long around today. It was difficult because the system couldn't read the subtext.
