At the AT&T divestiture in 1984, the United States was divided up into seven Regional Bell Operating Companies (RBOCs) or "Baby Bells". For a number of years after divestiture, these roughly stayed the same and operated much like they did under the original Bell System.

Things started to drastically change with the Telecommunications Act of 1996. These companies were now allowed to merge with other companies, and even with other RBOCs.

As of 2011, the concept of an RBOC has pretty much become a moot point, especially with the merger of CenturyLink and Qwest. However, many of us "old timers" remember how these companies pretty much did business the same way within a region.
