The breakup of the Bell System was mandated on January 8, 1982, by an agreed consent decree providing that AT&T Corporation would, as had been initially proposed by AT&T, relinquish control of the Bell Operating Companies that had provided local telephone service in the United States and Canada up until that point. This effectively took the monopoly that was the Bell System and split it into entirely separate companies that would continue to provide telephone service. AT&T would continue to be a provider of long-distance service, while the now-independent Regional Bell Operating Companies (RBOCs), nicknamed the 'Baby Bells', would provide local service, and would no longer be directly supplied with equipment from AT&T subsidiary Western Electric.

Nevada Bell spent nearly all of its history as a subsidiary of Pacific Bell, which is the reason Nevada Bell was not listed in Judge Harold Greene's Modification of Final Judgment, starting the breakup of AT&T.
