why isn't there a production studio which concentrates on crowd funded movies?

What you're describing is a movie producer, and as these appear in the Kickstarter space - as they are apparently doing now - I'd expect them to be essentially the same people that have been producing movies for the previous century.

The "conventional media", which is to say "the media", have the cameras and the lights. They have the theater-chain contracts and the distribution contracts. They have the agents' phone numbers and the union contracts and the favorite-son politicians and the sound stages within driving distance of your favorite actor's home. They know how to advertise and they have the lawyers and accountants.

And today's movie producers have connections to all of these things. Acquiring these connections is the hard part. Learning to put up a Kickstarter campaign is easy by comparison.

Kickstarter can change the shape of the "development" phase of movies, by giving producers (and writers or actors who want to self-produce) an alternative source of seed money and a way to cheaply drum up and demonstrate fan enthusiasm in advance of the product. But it will swiftly be incorporated into the existing media infrastructure, just as, say, the San Diego Comicon was.
