We’ve gotten this question a few times, just because some of our users and readers won’t watch anything below 720p as a matter of principle.
As far as we know, Dish Network’s TurboHD is the only sort of service like this we know of, and its a shame. There now would be a market for this kind of thing, assuming other providers would jump in. It seems many are happy with the service, but wish that Comcast or some other large provider would provide a service like this.
We don’t blame users, but feel free to chime in: would you pay for a high quality all HD service with hundreds of channels? Or did the failure of previous attempts seal the fate of ventures like these?
