The CW network has released an app for Apple TV that allows you to watch all of the channel's content for free--no cable TV subscription required.
This is another crack in the wall being defended by both the content owners (broadcast channels, cable channels) and the cable TV networks. It's a drip drip drip change, but OTT (Over The Top) offerings like CW are growing. Even if we all end up with several video subscriptions (e.g. Netflix, Amazon Prime, Hulu) the cost of video content is going to be much less in the long run, and we are going to be able to pick and choose exactly what we want to watch, rather than being forced to buy 100+ channels just to get a half dozen we are interested in.
