NBC Renews "American Ninja Warrior" "AGT" "Last Comic Standing".

American Ninja Warrior The network has renewed all three of its summer unscripted series

The network used its session in front of reporters at the Television Critics Association's summer press tour to announce additional season renewals for American Ninja Warrior, Last Comic Standing and America's Got Talent. As for the future of Hollywood Game Night, NBC Entertainment chairman Bob Greenblatt said the network is already in production on additional episodes of the series, which runs on a different schedule than its summer unscripted fare.

The series have been solid performers this summer for the network as it looks to unscripted fare and inexpensive scripted co-productions to keep the lights on in the typically lower-rated viewing months.

"The renewal of these three series is evidence that we continue to hit our stride in delivering quality entertainment to a broad viewership,” said Paul Telegdy, president of alternative and late night at NBC Entertainment. “All of the hardworking talented people on these shows — both behind and in front of the camera — should feel very proud of their achievements.”

American Ninja Warrior has been a standout on Mondays, recently besting CBS' summer hit Under the Dome in the demographic in head-to-head competition. The A. Smith and Co.-produced series, which this season saw multiple women conquer the famed Warped Wall, will be back for its sixth season.

Last Comic Standing, revived for an eighth season, returned with host JB Smoove and judges Roseanne Barr, Keenen Ivory Wayans and Russell Peters. The Wanda Sykes-produced revival returned on par with its last outing four years ago thanks to a steady lead-in from Hollywood Game Night. It will return next summer for season nine.

America's Got Talent has been a cornerstone of NBC's summer schedule for nine seasons. The reality competition show, hosted by Nick Cannon and featuring judges Howard Stern, Melanie Brown, Heidi Klum and Howie Mandel, has regularly ranked as summer's No. 1 series. The veteran series also recently bested ABC's big swing singing competition Rising Star in the latter's series debut with a special Sunday broadcast.

Unscripted fare is one of multiple strategies the broadcast networks have used to program in the summer. CBS helped change that game last summer with its Steven Spielberg-produced adaptation of Stephen King's Under the Dome.
