Leno was born in New Rochelle, New York. His homemaker mother, Catherine (nee Muir; 1911-1993), was born in Greenock, Scotland, and came to the United States at age 11. His father, Angelo (1910-1994), was an insurance salesman who was born in New York, to immigrants from Flumeri, Italy. Leno grew up in Andover, Massachusetts, and graduated from Andover High School.
In their new roles, neither O'Brien nor Leno succeeded in delivering the viewing audiences the network anticipated. On January 7, 2010, multiple media outlets reported that beginning March 1, 2010, Jay Leno would move from his 10 p.m. weeknight time slot to 11:35 p.m., due to a combination of pressure from local affiliates whose newscasts were suffering, and both Leno's and O'Brien's poor ratings. Leno's show would be shortened from an hour to 30 minutes. All NBC late night programming would be preempted by the 2010 Winter Olympics between February 15 and 26. This would move The Tonight Show to 12:05 a.m., a post-midnight timeslot for the first time in its history. O'Brien's contract stipulated that NBC could move the show back to 12:05 a.m. without penalty (a clause put in primarily to accommodate sports preemptions). On January 10, NBC confirmed that they would move Jay Leno out of primetime as of February 12 and intended to move him to late night as soon as possible. TMZ reported that O'Brien was given no advance notice of this change, and that NBC offered him two choices: an hour-long 12:05am time slot, or the option to leave the network. On January 12, O'Brien issued a press release that stated he would not continue with Tonight if it moved to a 12:05 a.m. time slot, saying, "I believe that delaying The Tonight Show into the next day to accommodate another comedy program will seriously damage what I consider to be the greatest franchise in the history of broadcasting. The Tonight Show at 12:05 simply isn't The Tonight Show." On January 21, it was announced that NBC had struck a deal with O'Brien. It was decided that O'Brien would leave The Tonight Show. The deal was made that O'Brien would receive a $33 million payout and that his staff of almost 200 would receive $12 million in the departure. O'Brien's final episode aired on Friday, January 22, 2010. Leno returned as host of The Tonight Show following the 2010 Winter Olympics on March 1, 2010. On July 1, 2010, Variety reported that total viewership for Jay Leno's Tonight Show had dropped from 5 million to 4 million for the second quarter of 2010, compared to the same period in 2009. Although this represented the lowest second-quarter ratings for the show since 1992, Tonight was still the most-watched late night program, ahead of ABC's Nightline (3.7 million) and Late Show with David Letterman (3.3 million).
