I believe congress has passed, quite a while ago, legislation requiring a "Choice" option for subs. But the cable and (sub)sat industry say that will increase the sub prices. For that and some other technical reasons, the're not going to implement a choice of "Choice" There have been hearings now and then on the issue, and enforcement of the "Choice" option, is again and again delayed. I had DTv, switched to Dish, as that option was cheaper to get channels I wanted to add, Dropped Dish when local cable added the same channels (again, because it was less out of the pocket ea. month). These channels were, until then, unavailable to the small independent cable operator, The channels were added, to the local line-up, after selling out to major cable operator. I do not know if any "cable" channels are still unavailable, to small ind. operators, or not. Considering Dish again, as the cable prices have, well, for what we get, gone nuts. I have calculated my Cable viewing costs during peak season(most scheduled hours of viewing, other than the local channels) at over 4 dollars and 50 cents per hour.
I can imagine quite a few content providers folding if the subs had a choice.
