Grimm has blossomed into a solid performer for NBC in the 14 episodes since its September premiere.  In recent weeks, the fairy tale drama hovered around 5 million viewers and 1.5 rating in the 18-49 demo.  In a vacuum, that's not very good.  But given the Friday night slot on a struggling network and an 87% increase in ratings after DVR, Grimm was a guaranteed renewal.  TV Line reports that indeed NBC committed to a renewal for a second season.  The network had little luck with the season's new dramas.  The Playboy Club, The Firm, and Prime Suspect are done for.  Awake, too, probably won't outlive 2012, and Smash is not the out-of-the-box hit NBC was hoping for.  Grimm is a true bright spot on a night where most broadcast television finds only darkness.
