Gotta state the obvious here, since I am a jerk like that (according to my wife): Does Dish not realize that if the "Alternative high-value channels." do not include a channel that airs "Mad Men", "The Walking Dead", "Breaking Bad", "The Killing" and "Hell On Wheels" that many people are going to be very unhappy?
The whole industry is losing touch with how people watch TV these days. People do not tune in to a channel to watch that channel - they tune in to watch a show. When it's over, they are very likely to go to another channel for a different show. They are actually most likely to be watching those shows time shifted, so they are really not watching the channel at all.
TV advertisers? Sorry, the game is over. No one will watch your commercials unless they are compelling. There are some commercials that are cool/funny/whatever, and I will actually skip back to watch them. But, generally, people pick and choose the shows they want to watch, regardless of the channel, and view them in the most convenient manner.
Dish is backing people like me into a corner. If they force me to pay ComCast to run cable (the quote I have heard is really high - many thousands), or, even easier, it looks like D* has an OTA HD addon, or I can buy an OTA HD recorder and make the switch. Either way, goodbye Dish. I would hate to do it, but I would if forced....
