What is an RBOC?
An RBOC is a Regional Bell Operating Company.
The RBOC's were created as part of the MFJ (Modified Final Judgement) which resulted in the breakup of AT&T in 1983.
AT&T was allowed to keep its long-distance services, but its national local service was broken up into seven geographic regions.
An RBOC can also be referred to as a Local Exchange Carrier (LEC).

The seven original RBOC's were:
