What's that, you didn't know AT&T was based in Texas? Yeah, ever since all those mergers (re-)created AT&T, its HQ has been in the former SBC offices in San Antonio, which is why certain services tend to roll out there first. It looks like the Alamo City isn't quite big enough for Ma Bell, though -- it's just announced that it's moving its corporate headquarters to Dallas in order to be closer to the airport. Yes, the airport. Dallas-Fort Worth Internation is country's third-largest airport, and AT&T wants travel to and from HQ to be more convenient and cost-effective. AT&T also has about 1,300 different suppliers and vendors in the Dallas area who employ some 45,000 people, so moving closer to them seems like a no-brainer. The company's Telecom Operations unit is staying put, however, so only about 700 of the 6,000 workers currently in San Antonio will be schlepping across the state. The transition should be completed within the year -- here's hoping some of those cost savings make their way down to us.
