telephone companies "SBC Pacific Bell" and "SBC Nevada Bell". In late 2002, the companies were rebranded again as simply "SBC". Meanwhile, employees of SBC working in California and Nevada who supported SBC's non-regulated services and/or services provided both within and outside California were transferred to other SBC subsidiaries, like "Pacific Telesis Shared Services" and "SBC Operations, Inc." However, for legal and regulatory purposes, employees supporting local regulated services were still employed by "Pacific Bell Telephone Company dba SBC California ("SBC California")", and "Nevada Bell dba SBC Nevada", which were the SBC subsidiaries that provided regulated local telephone services within the franchise territory in California and Nevada. On November 18, 2005, SBC completed its acquisition of AT&T Corp. to form AT&T Inc. Nevada and Pacific Bells are now known as Pacific Bell Telephone Company d/b/a AT&T California and Nevada Bell Telephone Company d/b/a AT&T Nevada. Pacific Telesis' companies as a whole business are known as AT&T West. In 2006, the company was dissolved into AT&T Teleholdings, which is the current name of the former Baby Bell Ameritech.
