\That's not going to happen until their programming contracts allow for it. Remember both Dish and DTV had ala carte, until channel owners immediately recognized a massive loss of revenue. Now they force the channels in certain packages based on contracts.
Oh, I understand. But these channel owners must know that no one watches their crap right? If 99.5% of subscribers don't listen to opera music, why even waste the time and space to it?
There is a reason so many people are "cutting the cord". Unless sat and cable get their act together they will be left in the dust - and it will happen, the history of technology is all the proof we need.
