Following a 2-script pickup last week, NBC has given new drama series Grimm a full-season pickup with a Back 9 order. The move comes after the rookie posted a 1.6 adult 18-49 rating this past Friday, even with the previous week to stop the show’s post-premiere slide. Additionally, NBC, which opted to keep Grimm in its original low-trafficked Friday 9 PM slot on the recently released midseason schedule, is giving the fairytale procedural a tryout in the Thursday 10 PM slot. A new Grimm episode will air on Thursday Dec. 8, followed by another original in the series’ regular Friday 9 PM berth the following night. “This series is turning the traditional procedural drama on its head and is attracting a loyal following for us on Friday nights,” NBC chairman Bob Greenblatt said. “We love where it’s going creatively and we’re excited to deliver more episodes to our audience.” Grimm exceeded expectations with its debut, which posted a 2.1 demo rating on Friday airing against Game 7 of the World Series. Season-to-date, it has averaged a 2.3/7 in adults 18-49 and 6.9 million viewers overall in “most current” averages and has improved NBC’s Friday 9 PM time period by 50% in adults 18-49 vs. last year in “live+same day.” Grimm also has proven a big DVR draw, growing 47% in 18-49 in Live+7, more than any new drama this fall. It has become the only freshman NBC drama to get a full-season order, joining comedies Up All Night and Whitney.

Inspired by the classic Grimm’s Fairy Tales, Grimm centers on Portland homicide Detective Nick Burkhardt (David Giuntoli) who discovers he is descended from an elite line of criminal profilers known as “Grimms,” charged with keeping balance between humanity and the mythological creatures of the world. Grimm is produced by Universal Television with Hazy Mills Prods. and GK Prods. It was created by Stephen Carpenter, David Greenwalt and Jim Kouf. Sean Hayes, Todd Milliner, David Greenwalt, Jim Kouf, Naren Shankar and Norberto Barba are the executive producers.
