NBC has announced it is renewing dramas CHICAGO FIRE, CHICAGO P.D. and GRIMM for the 2014-15 season. The network previously picked up THE BLACKLIST (season 2) PARKS AND RECREATION (season 7), THE VOICE (season 7) and "Celebrity Apprentice" (season 14). NBC is winning the season in adults 18-49, and ranked #1 for the first time in 10 years this late in the season. The network is up 20% versus one year ago, with its highest rating 25 weeks into the season in six years.Following the success of CHICAGO FIRE last year, Emmy Award-winning producer Dick Wolf's idea to build a second franchise in Chicago has become a reality with the renewal of mid-season success CHICAGO P.D. Both shows share the same creators and producers making it easy for characters and storylines to occasionally crossover seamlessly from one show to the other. This will be the case on the upcoming Tuesday, April 29 episode of CHICAGO FIRE - a massive bomb explosion sends the city into chaos, which will conclude the following night, Wednesday, April 30, on CHICAGO P.D. where the police officers deal with the fallout from the tragedy and try to find who was responsible for the blast.
