You know what'd be great? If there were simply reality TV channels. I mean, I know that several channels are like this already, but to just come out and own it by rebranding themselves. Those channels could pay for other shows that do better episodic narrative television, or actual in-depth historical/scientific documentaries (rather than the overly dramatized crap on the History Channel, which doesn't count). This would nicely segregate all the BS that's out there into easy-to-access locales, and permit folks who don't want to wait for the one half-hour of programming they can actually stomach.
So, bring on a separate channel for Eskimo Crack Wh***s In an R/V, Eat Dirt for Money, and Survivor in an Office Building.
