Jay Leno Jay Leno

The Jay Leno Show will debut on Sept. 14, NBC announced Tuesday. The show will air Monday through Friday at 10 pm/ET, eating up one-third of the Peacock's once-valuable prime time programming space.

Among the shows affected by the resulting schedule shuffle are Law & Order; SVU, which moves to Wednesdays at 9, and the original Law & Order, which unspools its record-tying 20th season on Fridays at 8. (See our full fall TV grid here for more details.)

Tonight Show successor Conan O'Brien will have 15 weeks of Leno-free air to get his footing with viewers. O'Brien's show premiered Monday, delivering the talker's best Monday night ratings in four years.
