Warehouse 13 is Syfy’s top 2010 series in total viewers and adults 25-54. So no surprise that the channel has given a pickup of 13 episodes to the dramedy which will return in 2011. Universal Cable Prods, which produces the series, has inked a development deal with Jack Kenny, who will return as exec producer and showrunner. During its second season, Warehouse 13 averaged 3.43 total viewers, 1.48M adults 18-49, and 1.78M adults 25-54.
