Wow, it's certainly the end of an era. SBC is buying ATT:

SBC Communications on Monday announced plans to acquire AT&T in a $16 billion deal, a move designed to bolster SBC's sales to enterprise customers nationwide and give it greater access to national and global networks.

I found it ironic a few years ago when Mobil and Exxon combined (mostly undoing the Standard Oil breakup). It looks like history is repeating itself, only at a highly accelerated rate.
