As more and more people cut the cable cord (or take down the satellite dish) the closer we come to every channel becoming an app / subscription service. CBS is ahead of the curve for the major networks, but all the major sports, HBO, etc. are already on board. And it's services like Apple TV that will provide packages of channels to order for "deals" just like cable's model since the 90s. I don't know if I'll be getting CBS All Access for Star Trek in January, but in 10 years it may be the only legal choice to access all of CBS' content.
