Remember, part of what made Netflix possible to begin with was the fact that the content they were licensing had already made its money through theatrical runs, cable deals and home video for movies, and original network fees and syndication rights for TV shows. So the content holders only had to worry about marginal revenue over negligible costs -- you can get very little for the content and still come out ahead. As streaming becomes a bigger and bigger piece of the pie, it canibalizes those other revenue channels, and more and more streaming money is required to make it revenue-positive. The market is reacting.
