Yahoo says it had trouble monetizing the original shows Community, Sin City Saints and Paul Feig's Other Space. Yahoo’s CFO Ken Goldman said the three high-profile projects “didn’t work the way that we hoped it would” and that we "couldn’t see a way to make money over time.” While today's news doesn’t sound good for the prospect of a Community movie, Variety reports that a film is "still in play — with or without Yahoo."

The Internet company didn’t spend much money marketing Community, and executives were reluctant to support its scripted shows long-term.

The Wall Street Journal explains the differences in costs, reporting that Yahoo, "according to people familiar with the matter," spent "roughly $2.7 million per episode for the show’s 13-episode sixth season. NBC had paid Sony only about $1 million per episode to air the previous (13-episode) season, the people said. Why the big price difference? Yahoo’s rate covered the full production costs of the show. Plus, Yahoo agreed to pay Sony a guarantee for syndication fees, the people said.”
