IN: The Jay Leno Show is an American talk show created by and starring Jay Leno. Premiering on NBC on September 14, 2009, the program aired on weeknights at 10:00 p.m. ET/PT through February 9, 2010. The program was modeled upon the format of a late night talk show--specifically, Jay Leno's incarnation of The Tonight Show, opening with a comedic monologue, followed by interviews with celebrity guests and other comedy segments. Sketches from The Tonight Show (including Headlines and Jaywalking) were carried over to The Jay Leno Show, along with new sketches.

Leno did not expect his show to beat competing first-run episodes, but to do better than reruns, in part because topical jokes benefit from the "immediacy" of the time slot versus 11:30 pm. A television analyst predicted that Leno would finish in "a safe third place" every night. NBC research before the show's debut indicated that fans of Leno would watch Leno two to three times a week. NBC saw a 1.5 rating for the show in the 18-49 demographic as "viable" and a 1.8 as a "home run". NBC told Leno that at a 1.5 rating, NBC makes $300 million a year. Tonight at 11:30 pm earned about a 1.3 to 1.5; the television audience at 10 pm is 40% larger than at 11:30 pm, and the network hoped Leno's audience would also grow. Industry observers have cited a range of ratings, from 1.7 to 2, as being necessary for the show to succeed at 10 pm. By comparison, 2.5 is generally necessary for a 10 pm drama to succeed; those that earned a 1.7 or less during the 2008-2009 season were generally cancelled. NBC's prime-time dramas averaged about 2 during 2008-2009. The first episode of The Jay Leno Show earned "fast national" estimates of 17.7 million viewers, an 11 Nielsen rating (5.1 among persons 18-49) and an 18 share, significantly above both his Tonight finale and the debut of The Tonight Show with Conan O'Brien in all categories. By the second week and competing against season premieres, the audience fell to six million viewers, still on par with or exceeding NBC projections. As of November 1, 2009, The Jay Leno Show has averaged a 1.98 in the adults 18-49 ratings and 6.594 million viewers. During the week before Christmas, the ratings dropped to 1.4 during the week. Prior to the controversy regarding the move of the Jay Leno Show to 11:35 p.m., viewership bottomed out at 4.799 million viewers, although there was a slight bump as word of the controversy broke. Though the show had been meeting the network's projections for the show itself, it has been severely detrimental to the ratings of the late local news on NBC affiliates. Several stations across the country have seen what is known as the "Leno Effect", where the lower audience for Leno (as compared to NBC's scripted prime time offerings) translated directly into a domino effect of severe audience drops for late local news (on the order of 25-30%), effects that NBC had underestimated.
