NBC’s Blindspot, already the fall season’s top-rated new series in adults 18-49, has become the first freshman series to get a Back 9 pickup, bringing its first-season order to a full-season 22 episodes. The order follows the network’s recent pickup of nine backup scripts for the thriller about a woman with no memories whose tattooed body holds the key to her past and to a vast and complex mystery.

nbclogo__130422182418-150x150Through three weeks, Blindspot has averaged a 2.7 rating in adults 18-49 and 9.6 million viewers overall in Live+Same Day. The show’s first two telecasts each have grown by 4.6 million viewers in Live+3, in both cases the biggest increases for those weeks among all broadcast and cable programs.

Blindspot, from Warner Bros. TV and Berlanti Prods., stars Sullivan Stapleton, Jaimie Alexander, Marianne Jean-Baptiste, Rob Brown, Audrey Esparza, Ukweli Roach and Ashley Johnson. Creator and writer Martin Gero serves as executive producer along with Greg Berlanti, Sarah Schechter, Mark Pellington and Marcos Siega. Pellington directed the pilot episode.
