Law & Order season 20
season of television series
The twentieth season of Law & Order premiered on NBC on September 25, 2009, which remained unchanged, for which it was moved from its previous time slot to air on Fridays at 8 p.m. ET for the NBC broadcast. L&O was moved to Monday nights on March 1, 2010, with a two-hour telecast at 9 p.m. ET, before settling into its new time slot at 10 p.m. the following week, March 8.
During the season, The Jay Leno Show in primetime was canceled, and Leno returned to the 11:35 pm Tonight Show because of affiliate dissatisfaction. Three more episodes of Law & Order were ordered to fill the primetime gap, increasing the number of episodes for the season to 23.
In early January, NBC announced the renewal of Law & Order for a 21st season. NBC's President of Primetime Entertainment at the time, Angela Bromstad, said, "I’m a "Law & Order" junkie... I wouldn’t want to be responsible for not having "Law & Order" break the record." However, the network abruptly canceled Law & Order on May 14 after 20 seasons on the air, tying it with Gunsmoke as American network television's longest-running regularly scheduled primetime drama.
