The SBC in the SBCGlobal is the short form for Southwestern Bell Corporation. And the email services of SBCGlobal were exclusive to the customers of SBCGlobal.

But later, the SBCGlobal was taken over by AT&T services, and it renamed the services of SBCGlobal after AT&T. But this didnt shut down the SBC email services. However, you cant create a new SBCGlobal email account. The old SBCGlobal email accounts are still accessible through AT&T email. As the email accounts of SBCGlobal were migrated to AT&T email after their merger.
