I personally believe in the exact opposite. Alternative channels exist today and are already used by alternative producers. But the problem, as I understand, is that Hollywood producers are somewhat tied to traditional channels. Because making a movie is so expensive, and today only traditional distribution returns your investment. Then after you spend a few million dollar making a movie, you'll find it a bit risky to try a new unproven distribution model.

It's naive to say that today anyone can make a movie, because cameras are cheaper. The average guy is still far from being able to produce anything remotely near a Hollywood production level. If that was true, if anyone (or any reasonably sized studio) could make a near Hollywood level movie. Then the competition would have killed them already. But that's a point where technology is specially important in fixing. The tools are still not cheap enough, but are getting cheaper. We can make them better.

Distribution is already here. But there's not enough content to distribute. I'd argue that the distribution problem is "reasonably well" solved today. The last piece of the puzzle is to solve content creation. We need to focus on building content, and tools that will democratize content creation. Not distribution.
