Houston adores U-verse. Since launching the service in the Texas city some 23 months ago, a whopping 100,000 residents have made the switch to AT&T's fiber-based programming service. In and of itself, that number isn't too significant, but when you consider that the carrier only has 549,000 U-verse TV customers (as of Q2 2008), you'll quickly realize how important the Houston market is to the company. Nearly 1 in 5 (18.2%) U-verse TV customers reside in or around Houston, and not surprisingly, the provider is continuing to expand its service in the region. Just remember Houston, AT&T owes you one if it hits that magical one million mark before 2009.
