The Trailer Channel

Dispense with the annoying hosts, the infomercials, the "making of", and the celebrity interviews. Just show the trailers, already. We all know these are the best part of going to the movies, anyway. 8)

Trailers are works of art unto themselves. Even though they borrow heavily from the full-length features they are advertising, they usually manage to get in all the best visuals, the wittiest lines, or the most dramatic plot points. Most are more interesting to watch than the movies themselves, especially for low-qualitiy films. And if you don't like a given trailer, don't worry -- it will be over in the length of time it takes to wait through a conventional commercial block.

The movie industry would probably have some amount of economic interest in subsidizing such an endeavor; certainly new video-on-demand services and rental places would benefit from people serendipitously discovering movies that interest them.

Everyone from bored couch potatoes to history buffs might have a general interest; trailers from particular genres might be broadcast in particular timeslots to attract viewers with interests in everything from sci-fi to Hitchcock to "inspired by real-life events" to documentaries.
