What timeslot did Leno have?
Leno started a primetime talk show, titled The Jay Leno Show, which aired weeknights at 10:00pm ET.
Why was the Jay Leno Show moved?
Multiple media outlets reported that beginning March 1, 2010, Jay Leno would move his 10 p.m. weeknight time slot to 11:35 p.m., due to both Leno's and O'Brien's poor ratings.

Question: Did the timeslot change help or hurt ratings?
