Jay Leno

Leno made his first appearance on The Tonight Show on March 2, 1977, performing a comedy routine. During the 1970s, he had minor roles in several television series and films, first in the 1976 episode "J.J. in Trouble" of Good Times, and the same year in the pilot of Holmes & Yo-Yo. After an uncredited appearance in the 1977 film Fun with Dick and Jane, he played more prominent roles in 1978 in American Hot Wax and Silver Bears. His other film and television appearances from that period include Almost Heaven (1978), "Going Nowhere" (1979) on One Day at a Time, Americathon (1979), Polyester (1981), "The Wild One" (1981) on Alice, and both "Feminine Mistake" (1979) and "Do the Carmine" (1983) on Laverne & Shirley. His only starring film role was the 1989 direct-to-video Collision Course, with Pat Morita. He also appeared numerous times on Late Night with David Letterman.

He also appeared on three weeks of the short-lived NBC game show Match Game-Hollywood Squares Hour in 1983 and 1984.

Starting in 1986, Leno was a regular substitute host for Johnny Carson on The Tonight Show. In 1992, he replaced Carson as host amid controversy with David Letterman, who had been hosting Late Night with David Letterman since 1982 (which aired after The Tonight Show), and whom many—including Carson himself—expected to be Carson's successor. The story of this turbulent transition became the basis of a book and a movie. Leno continued to perform as a stand-up comedian throughout his Tonight Show tenure. In 1988, he received a contract extension with NBC itself. The July 1995 episode of The Tonight Show which featured an interview with Hugh Grant (who had been arrested for receiving oral sex in a public place from a prostitute) saw Leno rate higher than Letterman for the first time.

In 2004, Leno signed a contract extension with NBC to retain him as host of The Tonight Show until 2009. Later in 2004, Conan O'Brien signed a contract with NBC to become the show's host in 2009, replacing Leno at that time.

During the 2007–08 Writers Guild of America strike, Leno was accused of violating WGA guidelines by writing his own monologue for The Tonight Show. NBC and Leno claimed there were private meetings with the WGA where a secret agreement was reached allowing this; the WGA denied such meetings. Leno answered questions in front of the Writers Guild of America, West trial committee in February 2009 and June 2009, and when the WGAW published its list of strikebreakers on August 11, 2009, Leno was not on it.

On April 23, 2009, Leno checked himself into a hospital with an undisclosed illness. He was released the following day and returned to work on Monday, April 27. The two subsequently canceled Tonight Show episodes for April 23 and 24 were his first in 17 years as host. The illness was not initially disclosed, but Leno later told People magazine that it was for exhaustion.

During the 2005 trial of Michael Jackson over allegations of child molestation, Leno was one of a few celebrities who appeared as defense witnesses. In his testimony regarding a phone conversation with the accuser, Leno testified that he was not asked for any money and there did not appear to be any coaching — but the calls seemed unusual and scripted.

As a result, Leno was initially not allowed to tell jokes about Jackson or the case, which had been a fixture of The Tonight Show's opening monologue in particular. But he and his show's writers used a legal loophole by having Leno briefly step aside while stand-in comedians took the stage and told jokes about the trial. These stand-ins included Roseanne Barr, Drew Carey, Brad Garrett and Dennis Miller. The gag order was challenged, and the court ruled that Leno could continue telling jokes about the trial as long as he did not discuss his testimony. Leno celebrated by devoting an entire monologue to Michael Jackson jokes.

Because Leno's show continued to lead all late-night programming in the Nielsen ratings, the pending expiration of his contract led to speculation about whether he would become a late-night host for another network when his commitment to NBC expired. He left The Tonight Show on Friday, May 29, 2009, and Conan O'Brien took over on June 1, 2009.

On December 8, 2008, it was reported that Leno would remain on NBC and move to a new hour-long show at 10 p.m. Eastern Time (9 p.m. Central Time) five nights a week. It would follow a similar format to The Tonight Show, be recorded in the same studio, and retain many of Leno's most popular segments, while O'Brien continued to host The Tonight Show.

Leno's new show, The Jay Leno Show, debuted on September 14, 2009. It was announced at the Television Critics Association summer press tour that it would feature one or two celebrities, occasional musical guests, and keep the popular "Headlines" segments, which would be near the end of the show. First guests included Jerry Seinfeld, Oprah Winfrey (via satellite), and a short sit-down with Kanye West discussing his controversy at the 2009 MTV Video Music Awards, which had occurred the night before.

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, 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 also be preempted by the 2010 Winter Olympics between February 15 and 26, moving The Tonight Show to 12:05 a.m., the first post-midnight timeslot in its history. O'Brien's contract stipulated that NBC could move the show ahead to 12:05 a.m. without penalty (a clause included primarily to accommodate sports preemptions).

On January 10, NBC confirmed that it would move Leno out of primetime as of February 12 and 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 12:05 a.m. time slot, or the option to leave the network. On January 12, O'Brien issued a press release that 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: He would leave The Tonight Show, receive a $33 million payout, and his staff of almost 200 would receive $12 million in the departure. His 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 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 it represented the show's lowest second-quarter ratings 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).

On April 3, 2013, NBC announced that Leno would leave The Tonight Show in spring 2014, with Jimmy Fallon as his designated successor.

Leno's final show as the host of The Tonight Show was on February 6, 2014, with guests Billy Crystal (who was the first guest on the first version of Leno's show), musical guest Garth Brooks, and surprise guests Jack Black, Kim Kardashian, Jim Parsons, Sheryl Crow, Chris Paul, Carol Burnett and Oprah Winfrey.

Leno has maintained an active schedule as a touring stand-up comedian, doing an average of 200 live performances a year in venues across the United States and Canada and at charity events and USO tours. He has also appeared on the Tonight Show with Jimmy Fallon and Late Night with Seth Meyers, and was a guest on the finale of The Late Late Show with Craig Ferguson. He appeared in a cameo role drilling and tormenting James Corden in a facetious boot camp for talk-show hosts on the premiere of The Late Late Show with James Corden. He declined an invitation to appear on Late Show with David Letterman despite speculation he would appear on the show's finale in 2015, although he had appeared with Letterman along with Winfrey in a Late Show commercial airing during Super Bowl XLIV in 2010.

Leno hosted a one-hour Jay Leno's Garage special on CNBC in 2014, and the show returned as a primetime series on the cable channel from 2015 until 2022. The series was canceled in January 2023 after seven seasons due to a decision by the channel to re-emphasize business-oriented programming.

Leno also had a recurring role in the Tim Allen comedy series Last Man Standing since season 5, playing a mechanic, Joe Leonard, in a store operated by Allen's character, Mike Baxter.

Leno hosted the third revival of the game show You Bet Your Life for two seasons, from 2021 until 2023. The show was renewed for a third season but was cancelled in August 2023 after Leno refused to cross the picket line during the 2023 Writers Guild of America strike, after Fox First Run offered stations two other syndicated game shows to fill You Bet Your Life's timeslot during the strike, instead of reruns.

Leno also does voice acting, such as The Crimson Chin on The Fairly OddParents from 2001 to 2016 and Billy Beagle of Mickey and the Roadster Racers.

In 2019, Leno was a guest judge on season 14 of America's Got Talent where he pressed the Golden Buzzer for opera singer Emanne Beasha.

In 2023, Leno returned to NBC to appear as a celebrity guest judge on the two-episode season finale of Hot Wheels: Ultimate Challenge.

Leno has faced criticism for his perceived role in the 2010 Tonight Show conflict. Critics have cited a 2004 Tonight Show clip where Leno said he would allow O'Brien to take over without incident. At the time, Leno said he did not want O'Brien to leave for a competing network, adding, "I'll be 59 when [the switch occurs]. That's five years from now. There's really only one person who could have done this into his 60s, and that was Johnny Carson; I think it's fair to say I'm no Johnny Carson." Leno also described The Tonight Show as a dynasty, saying, "You hold it and hand it off to the next person. And I don't want to see all the fighting." At the end of the segment, he said, "Conan, it's yours! See you in five years, buddy!"

Rosie O'Donnell was among O'Brien's most vehement supporters, calling Leno a "bully" and his actions "classless and kind of career-defining". Bill Zehme, the co-author of Leno's autobiography Leading with My Chin, told the Los Angeles Times, "The thing Leno should do is walk, period. He's got everything to lose in terms of public popularity by going back. People will look at him differently. He'll be viewed as the bad guy."

In 2009, Leno received criticism for asking rapper Kanye West how his recently deceased mother, Donda West, would have felt about the incident at the 2009 VMAs, causing West to begin crying live on air.

Howard Stern has also been a critic of Leno before and following his Tonight Show timeslot-change announcement; Stern appeared on Late Night with Conan O'Brien in 2006 and said he felt it was unlikely that Leno would ever willingly give up The Tonight Show. During the conflict, Stern made many negative remarks about Leno as a guest on Late Show with David Letterman.

Jimmy Kimmel discussed his appearance on Leno's show during an interview with Marc Maron for the latter's podcast in 2012. Kimmel stated that he felt O'Brien was not given a proper chance, but that he was also motivated by his own history with Leno. According to Kimmel, Leno had some years prior been in serious discussions with ABC about the possibility of jumping ship from NBC. During this period, Leno initiated a friendship with Kimmel, wanting to ensure that they would be on good terms if the move was made. (Under that scenario, Leno would have taken Kimmel's time slot and become his lead-in.) However, after Leno made the arrangement to remain at NBC, "those conversations were gone," according to Kimmel. Realizing that Leno's relationship with him had been artificial, Kimmel felt "worked over," reasoning that Leno was using the ABC discussions as a bargaining tactic to try to get his old job back.

John Oliver has also criticized Leno for his coverage of the Clinton-Lewinsky scandal on The Tonight Show in an episode on public shaming.

Leno has also been criticized for the perceived change in the content of his monologues from his previous stand-up material. Actor and comedian Patton Oswalt was among the celebrities who openly voiced disappointment with Leno, saying, "Comedians who don't like Jay Leno now, and I'm one of them, we're not like, 'Jay Leno sucks'; it's that we're so hurt and disappointed that one of the best comedians of our generation ... willfully has shut the switch off."

In August 2020, Leno faced criticism for expressing support for Ellen DeGeneres despite a workplace investigation into toxic behavior and sexual misconduct and harassment claims against producers of The Ellen DeGeneres Show.

NBC Sports chairman and former Saturday Night Live producer Dick Ebersol spoke out against all who had criticized Leno, calling them "chicken-hearted and gutless". Jeff Gaspin, then chairman of NBC Universal Television Entertainment, also defended Leno, saying, "This has definitely crossed the line. Jay Leno is the consummate professional and one of the hardest-working people in television. It's a shame that he's being pulled into this." Fellow comedians Paul Reiser, Jerry Seinfeld and Jim Norton (a frequent contributor to The Tonight Show) also voiced support for Leno.

Responding to the mounting criticism, Leno said NBC had assured him that O'Brien was willing to accept the proposed arrangement and that they would not let either host out of his contract. He also said that the situation was "all business", and that all of the decisions were made by NBC. He appeared on the January 28, 2010 episode of The Oprah Winfrey Show in an attempt to repair some of the damage done to his public image.

Leno has been married to Mavis Leno since 1980. In 1993, during his first season as host of The Tonight Show, Leno's mother died at the age of 82; and the next year, his father died at 84. Leno's older brother, Patrick, a Vietnam veteran and graduate of Yale Law School, died of cancer in 2002 at the age of 62. In 2024, it was disclosed that Mavis Leno is suffering from an advanced form of dementia when the Los Angeles Superior Court granted Jay Leno conservatorship of the couple's joint estate as she experiences periods of disorientation and at times does not know who her husband is or her own date of birth.

Leno is known for his prominent jaw, which has been described as mandibular prognathism. In the book Leading with My Chin, he says he was aware of surgery that could reset his mandible, but that he did not wish to endure a prolonged healing period with his jaws wired shut.

Leno is dyslexic. He claims to need only four or five hours of sleep each night. He does not consume alcohol, smoke, or gamble. He spends much of his free time visiting car collections and working in his private garage.

Leno has claimed that he has not spent any of the money he earned from The Tonight Show, but lives off his money from his stand-up routines. He reportedly earned $32 million in 2005. In 2014, he received an Honorary Doctor of Humane Letters degree from Emerson College, where he also delivered the commencement speech. He also received an Honorary Doctorate of Humane Letters from Academy of Art University in 2021.

On November 12, 2022, Leno suffered "serious burns" to his face and hands when a vehicle at his Los Angeles garage burst into flames. As part of the treatment, he received a "new ear". On January 17, 2023, he sustained multiple broken bones after falling off a motorcycle.

In 2001, he and his wife donated $100,000 to the Feminist Majority Foundation's campaign to stop gender apartheid in Afghanistan, to educate the public regarding the plight of women in Afghanistan under Taliban rule. Mavis Leno is on the board of the Feminist Majority.

In 2009, he donated $100,000 to a scholarship fund at Salem State College (now Salem State University) in honor of Lennie Sogoloff, who gave Leno his start at his jazz club, Lennie's-on-the-Turnpike.

In August 2012, Leno auctioned his Fiat 500, which was sold for $385,000 with all the proceeds going to a charity that helps wounded war veterans recover by providing them with temporary housing.

As of November 2022, Leno sponsored two scholarships at McPherson College.

Since 1985, Leno has been the Grand Marshal for the Love Ride, a motorcycle charity event which since its founding in 1984 has raised nearly $14 million for charities benefiting muscular dystrophy research, Autism Speaks, and in 2001, the September 11 attacks recovery.

Leno owns approximately 286 vehicles (169 cars and 117 motorcycles). He also has a website and a TV program called Jay Leno's Garage, which contains video clips and photos of his car collection in detail, as well as other vehicles of interest to him. Leno's garage manager is Bernard Juchli. Among his collection are two Doble steam cars, a sedan and a roadster that were owned by Howard Hughes, the fifth Duesenberg Model X known to survive, and one of nine remaining 1963 Chrysler Turbine Cars. The collection also includes three antique electric cars — the 1909 Baker Motor Vehicle is his wife Mavis's favorite car.

He has a regular column in Popular Mechanics which showcases his car collection and gives advice about various automotive topics, including restoration and unique models, such as his jet-powered motorcycle and solar-powered hybrid. Leno also writes occasional "Motormouth" articles for The Sunday Times, reviewing high-end sports cars and giving his humorous take on motoring matters.

Leno opened his garage to Team Bondi, the company that developed the 2011 video game L.A. Noire, which is set in Los Angeles in the late-1940s. Leno's collection contains almost 100 cars from this period, and allowed the team to create their images as accurately as possible.

Hosting the 2014 Genesis Prize award ceremony in Jerusalem, Leno made jokes mocking then-President Barack Obama and then-Secretary of State John Kerry, accusing Obama of "trying to break" the U.S.'s relationship with Israel.

In a 2015 interview with The Jerusalem Post, Leno said, "I always considered Israel as not only the only democracy in the Middle East, I think it's the purest, because every Israeli voter seems to have his own political party." He also added about Israel's relations with other Middle Eastern countries: "Israel is so efficient in defending itself and so good at it, that to the rest of the world it looks like bullying."

In a 2024 interview on Piers Morgan Uncensored, Leno said that he is "not a fan" of former President Donald Trump. Of President Joe Biden, Leno said: "I like him. I think he's a good guy. And, you know, the economy's doing pretty good!"
