Try half a dozen - not one or two. Different ownership groups. HD-2 apathy by owners is a problem - at least here in Houston, the 6th largest market.
They're only going to care if they're bringing in revenue. Have the station groups in Houston embraced the trend of pairing HD2s with translators? I can't imagine a 250 watt translator covering much of the sprawling metro area, but it is probably going to be the only way your stations get any attention.
HD is getting to finally be a huge deal here in Alabama because of the potential for feeding translators. I dunno if we're just ahead of the curve (for once) or what, but it's really made the station groups focus on keeping the HD2/3 channels going once they are paired up with a translator. To give an idea of how much this is being used, consider this: Birmingham, market #57, has 9 translators being fed by HD2/3 programming. Three or four are doing well in the ratings. HD-fed translators outnumber AM-fed ones by 3:1 in the metro area. In Montgomery, market 150, they have four HD fed and five AM fed translators. Tuscaloosa has two HD-fed with two more in the wings, Huntsville has one, Mobile has one or two now… Even Selma has one. Columbus, GA has 4 HD-fed translators. Auburn has one or two, even.
I think the only real ranked market that has not embraced HDs feeding translators is Dothan, and it's basically the land that time forgot, anyway. I don't think they even have any HD commercial broadcasts at all. Muscle Shoals/Florence is not a rated market, I don't think, and they don't have any HD either. But in the other areas, it's really taken off. And as a consequence, the stations are programming the HD2s better and making sure they stay lit all the time.
