These companies have since merged, leaving only 4 regional telephone companies in the United States. In 1998, Southwestern Bell changed its name to SBC Communications[?] and acquired Pacific Bell and Ameritech. In 1997, NYNEX was acquired by Bell Atlantic, which later, in 2000, merged with GTE to form Verizon. In 2000, US WEST was merged into Qwest, a fiber optic company. BellSouth is the only RBOC that remains as originally conceived, and is the only company that still carries the "Bell" name. BellSouth still uses the last Bell logo, designed in 1969.
