I saw on one of the news channels this morning that FOX is exploring starting their own TV APP similar to Sling that would include all the FOX channels and regional sports channels. Some cable companies also thinking about cordless TV.
I pay $20/ month for Sling. As long as Fox isn't outrageous, I would spend $10-$15 for their program. It would have to include FX, and the Fox Sports 1 and the other Sports channels, but I am game.
I don't know why more stations aren't doing this. They could make as much money (if not more than they are now), and they wouldn't be held back by Directv, Dish, etc.
