Jericho is an American serial drama produced by CBS Paramount Network Television, with executive producers Jon Turteltaub, Stephen Chbosky and Carol Barbee.
The first season of the show premiered Wednesday, September 20, 2006, on CBS and went on hiatus after the episode of November 29, 2006. It returned February 21, 2007, after a special recapping the first 11 episodes on February 14, 2007, and concluded with a cliffhanger episode on May 9, 2007. Lackluster ratings prompted concern, as the show hit a ratings low in early April. The ratings were down 25% following the nearly three-month hiatus and subsequent return opposite American Idol. During its first season, it ranked 48th, with an average of 9.5 million viewers in the United States. Other Wednesday night programs it competed with were Lost and South Park.
Though the producers seemed confident of a second season, the series was initially canceled by CBS in May 2007. However, after a grassroots campaign to revive the series, CBS officially announced on June 6, 2007 that it had purchased seven new episodes of Jericho for broadcast as a mid-season replacement.
