I heard the same about the movie industry: it used to be run by movie people, now it's run by finance people. The greedy producers of old came from the industry and understood the business; today's greedy producers don't understand anything about movies, so if you're pitching them a project, you need to speak their language: here's a market niche, here's similar projects that have been profitable, here's the return on investment we can expect.

I wish i knew how true that is, but it does seem to explain a lot of what we see from Hollywood these days.
