NBC has renewed Community for a 13-episode fourth season, as per The Hollywood Reporter. The deal is not for a final season, like the deal for 30 Rock announced earlier today, but there is no news on whether or not there will be the potential for more episodes if the show exceeds expectations (or simply performs slightly better than the new comedies on the network). Presumably, that information will become more clear when NBC announces whether the show will be on in the fall or will be pushed to midseason (which would make a full back nine order more difficult). If it aired in the fall, Community would become, in effect, one of NBC's new shows, competing with them all to be one of those picked up for the back nine. There is precedent for this in recent NBC history, with Chuck receiving a 13-episode pickup for its fourth season, an order that was increased by 11 episodes when the episodes that aired in the fall over-performed expectations. (The spring episodes then quickly sank into the ratings toilet.)
