In October 2000, AT&T announced a restructuring plan to create a family of four businesses, each operating under the "AT&T" brand, committed to uniform standards of quality. Under the plan, which is expected to be complete in 2002, each of these four businesses will become publicly held, trading as either a common stock or tracking stock. On July 9, 2001, AT&T Wireless was split off as an independent, publicly-traded company.
