Look out, pay-TV providers -- AT&T just broke out the big stick and announced that it's now beaming at least 100 high-def channels in every last one of its markets. In fact, that's more HD channels than any local cable competitor in any existing U-verse
market. Just in case you were wondering, customers won't be dinged any extra for the new additions, with HD service being included with the U450 tier and available for $10 per month with any other U-verse TV package. So yeah, we're stoked as can be for those with access to this stuff, but can we get a little market expansion going on now that the century mark has been passed?
