Dude, Fox AND CNN are by far the majority watched news channels. Saying either "isn't being watched by any appreciable audience" is a bias to content speaking, not facts. Dish doesn't want to lose EITHER, no matter which at this point in time is #1 because they both have been #1 at different points in time and these contracts aren't about today but the ever evolving future. And if you think in the same situation Charlie wouldn't do the same to Fox, you don't know Charlie. First off, no one is losing anything, its the way these deals are negotiated more and more over time, regardless of which channel it is and what content it provides as evidenced by Dish dropping AMC and some of the hottest shows on cable, The Walking Dead, Mad Men and Breaking Bad with very loyal fans in 2012. In 2o12, Walking Dead was the most watched cable show for the year overall and in the key demographic groups.
