Not to be outdone by Time Warner Cable in San Antonio, it looks like Comcast is getting in on the "add HD channels" craze. Well, at least in the Houston market it acquired from TWC this summer. Additions to the lineup include the HD-flavors of: National Geographic, USA, A&E, History Channel, HGTV, Food Network and CNN. With this move, Comcast reaches 30 HD channels in Houston. Sure it's no wave of channels like DirecTV is experiencing, but kudos to Comcast for making sure its newly-acquired customers didn't feel like they were forgotten about. If they can get some of that TiVo goodness out to Houston, that would be icing on the cake.
