The AT&T you see today is a completely different company. For all intents and purposes, it is SBC (Southwestern Bell Communications).

In 1996, Bell Labs, Western Electric, and AT&T Technologies were spun out to create Lucent.

Lucent merged with Alcatel to form Alcatel-Lucent in 2006.

Alcatel-Lucent was purchased by Nokia in 2016.

AT&T Wireless was purchased by Cingular in 2004 (joint venture between BellSouth and SBC).

The original AT&T was purchased by SBC in 2005.

The new AT&T (SBC) bought BellSouth in 2006.
