ADDITIONAL NOTES: renewed through the 2013-14 season (the show's second of 22 episodes) on 4/26/13
DESCRIPTION: (from NBC's press release, April 2013) NBC has announced the renewal of five key drama series for the 2013-14 season: "Revolution," "Chicago Fire," "Parenthood," "Grimm" and "Law & Order: Special Victims Unit." All have been given 22-episode orders. "Chicago Fire," from Emmy Award-winning executive producer Dick Wolf and creators Derek Haas and Michael Brandt, goes inside a Windy City firehouse and the lives of those who engage in one of our nation's noblest professions. In addition to Wolf, Haas and Brandt, executive producers also include Matt Olmstead, Joe Chappelle, Danielle Gelber and Peter Jankowski. The series is produced by Universal Television and Wolf Films. "Chicago Fire" has topped its premiere audience of 6.6 million persons a total of eight times this season, and the only other new drama on the broadcast networks to have done it even once this season is NBC's "Hannibal." "Chicago Fire" originals have improved the time period versus year-ago results by 24 percent ("live plus same day").
