While some of the new fall series have yet to learn their fate for the remainder of their first seasons, NBC’s breakout new drama Blindspot — the first to get backup scripts and full-season freshman order — has received a very early second-season renewal. The series, starring Sullivan Stapleton and Jaimie Alexander, ranks as the No. 1 new fall series among adults 18-49.

Blindspot is off to a very strong start — averaging a 3.7 rating in adults 18-49 and 12.7 million viewers overall so far this nbclogo__130422182418-150x150season, according to “most current” Nielsen averages, dominating its Monday 10 PM time slot. Still such an early renewal is unusual. Another NBC drama in the same time period, Revolution, also had a blazing start but started to lose steam by the second half of Season 1 and faded in its second season. With its procedural element, Blindspot is more in the vein of NBC’s other Monday 10 PM entry, The Blacklist, which keeps going, now in its third season, on a challenging new night.

Blindspot is also one of the most time-shifted shows on television, growing by 71% so far this season in adults 18-49 rating from Live+Same Day to Live+7 (from a 2.65 to a 4.54) and by more than 5.7 million viewers overall (9.3 million to 15.1 million).

“We are over the moon with the success of Blindspot and want to thank our producers and amazing cast for creating one of the most riveting shows on television,” said Jennifer Salke, President of NBC Entertainment. “Jaimie and Sullivan have done an amazing job of ratcheting up the tension each week in trying to unravel the mystery of Jane’s tattoos.”

A beautiful woman, with no memories of her past, is found naked in Times Square with her body fully covered in intricate tattoos. Her discovery sets off a vast and complex mystery that immediately ignites the attention of the FBI, who begin to follow the road map on her body to reveal a larger conspiracy of crime while bringing her closer to discovering the truth about her identity. Stapleton and Alexander lead the cast of the show, which also includes Marianne Jean-Baptiste, Rob Brown, Audrey Esparza, Ukweli Roach and Ashley Johnson.

Martin Gero created Blindspot and executive produces with Greg Berlanti, Sarah Schechter, Mark Pellington and Marcos Siega for Warner Bros. TV and Greg Berlanti Prods.
