No, they bought AT&T, which had an ISP business, a long distance business, a private line business, and AT&T Labs, as well as other miscellaneous pieces like the brand name.  We can wonder if AT&T would have survived as an independent company, but it was a going concern and not in bankruptcy at the time of the transaction.  But yes, SBC is the controlling piece of the new AT&T.

As for the two /8s -- not quite.  Back in the 1980s, AT&T got 12/8.  We soon learned that we couldn't make good use of it, since multiple levels of subnetting didn't exist.  We offered it back to Postel in exchange for 135/8 -- i.e., the equivalent in class B space -- but Postel said to keep 12/8 since no one else could use it, either.  This was all long before addresses were tight.  When AT&T decided to go into the ISP business, circa 1995, 12/8 was still lying around, unused except for a security experiment I was running.*    However, a good chunk of 135/8 went to Lucent (now Alcatel-Lucent) in 1996, though I don't know how much.

*The early sequence number guessing attack tools required a dead host that would be impersonated by the attacker.  By chance, one of the early tools used something in 12/8.  I started announcing it from Murray Hill, to catch the back-scatter from the victims.  We found some of that; we also found lots of folks who were using 12/8 themselves, probably internally.
