Jimmy Fallon (born September 19, 1974, New York, New York, U.S.) is an American comedian, talk show host, and writer who first garnered attention for his exuberant presence on the sketch comedy show Saturday Night Live (SNL; 1998–2004) and later became host of Late Night with Jimmy Fallon (2009–14) and The Tonight Show (2014– ).

Education and SNL

Fallon attended the College of St. Rose, Albany, New York, but left before completing a degree to pursue a career in comedy in Los Angeles. Within a few years, however, he went to New York City to audition for a spot on SNL, and he joined the cast in 1998. The SNL format served as a showcase for Fallon’s comedic impressions. He often portrayed celebrities and created memorable characters such as Jarret the stoner and Nick Burns, a patronizing computer expert. On his last four seasons, Fallon cohosted SNL’s “Weekend Update” segment with fellow comedian Tina Fey. In the skit the two starred as coanchors, mixing humor with contemporary news stories.

Movies

In 2004 Fallon left SNL to pursue a movie career. He starred in the comedy Taxi (2004) and in the romantic comedy Fever Pitch (2005) and also had parts in the drama Factory Girl (2006) and the comedy-drama Whip It (2009). However, he failed to become a big box-office draw, and he turned his focus to television. However, Fallon continued to occasionally act in movies, and he appeared as himself in Spirited (2022) and Jack in Time for Christmas (2024).

Talk show host

In March 2009 Fallon replaced talk show host Conan O’Brien on Late Night with Conan O’Brien. Late Night with Jimmy Fallon featured comedy sketches, impersonations, musical performances (including guitar solos by Fallon), celebrity guests, and one-on-one upbeat interviews. Fallon’s enthusiasm and energy were infectious. He persuaded guests to participate in a number of offbeat sketches; notably, U.S. Pres. Barack Obama appeared with him in “Slow Jam the News,” a segment in which they recited headlines over a sexy funk groove.

Fallon took over one of the most-coveted chairs in late-night television when in February 2014 he succeeded Jay Leno as host of The Tonight Show. Fallon became the sixth host of the iconic program, which premiered in 1954. At Fallon’s request The Tonight Show was moved from Burbank, California (where former host Johnny Carson had relocated it in 1972), and returned to the same studio that Carson had previously used in Rockefeller Center, New York City. In addition, his longtime executive producer, Lorne Michaels, and his house band, the hip-hop group the Roots, joined The Tonight Show.

During this time, Fallon also made guest appearances on various TV shows, often cast as himself. These credits include Gossip Girl, 30 Rock, Only Murders in the Building, and Fleishman Is in Trouble.

Other activities

Besides fulfilling his hosting duties, Fallon established a strong presence on social media. He had millions of followers on Twitter, and some of the videos that he created with celebrities went viral on YouTube. In addition, he wrote several books, including Your Baby’s First Word Will Be Dada (2015), Everything Is Mama (2017), This Is Baby (2019), and 5 More Sleeps ‘til Halloween (2024), all of which were for children. In 2012 and 2014 Fallon earned Emmy Awards for outstanding guest actor for hosting SNL.

Saturday Night Live

American television program
Also known as: “NBC’s Saturday Night”, “SNL”
Original name (1975–77):
NBC’s Saturday Night
Awards And Honors:
Emmy Award
Peabody Award

Saturday Night Live (SNL), American sketch comedy and variety television series that has aired on Saturday nights on the National Broadcasting Company (NBC) network since 1975, becoming one of the longest-running programs in television. The series is a fixture of NBC programming and a landmark in American television.

Development and format

NBC developed Saturday Night Live as an edgy comedy series designed to appeal to viewers ages 18 to 34, and, notwithstanding a few slumps, the show has consistently attracted new viewers who have entered that demographic group while remaining a favorite with many who have moved out of it. The 90-minute program was created by Dick Ebersol and Lorne Michaels, the latter of whom continues as a writer and executive producer of the show, after having taken a brief hiatus in the early 1980s.

Each episode features the show’s regular ensemble of comedic actors, as well as a guest host and a musical guest. The show always begins with an opening sketch that ends with the signature phrase, “Live from New York, it’s Saturday Night!” Filming before a studio audience and broadcasting live (with Western time zones viewing a tape delay) has given the show its without-a-net edge and has led to many memorable moments, as well as a few controversies and missteps (perhaps most notably, in 1992, Irish singer Sinéad O’Connor ripping up a photograph of Pope John Paul II on camera, prompting an outraged response from thousands of viewers).

Not Ready for Primetime Players

Mixing topical and political subject matter with observational humor and parody, SNL borrowed elements from the format of British television’s pioneering That Was the Week That Was (1962–63, hosted by David Frost). But beyond those roots, from its inception it has been firmly grounded in the form of improvisational comedy developed in Chicago in the 1950s and ’60s by the Compass Players and at Second City. Indeed, Second City (both its original Chicago and its Toronto companies) and the Los Angeles improvisation group the Groundlings provided many of the performers who have made up SNL’s ensemble, beginning with its original cast, known as the Not Ready for Primetime Players—Dan Aykroyd, John Belushi, Chevy Chase, Jane Curtin, Garrett Morris, Laraine Newman, and Gilda Radner. (This improvisation tradition also gave rise to Second City TV, which appeared first on Canadian television [1976–80] and then on NBC [1981–83], to the American Broadcasting Company’s Fridays [1980–82], and to the Fox network’s In Living Color [1990–94] and MADtv [1995–2009], among other programs.) Similarly, the brilliantly warped satire of National Lampoon magazine (and the National Lampoon Radio Hour [1973–74]) was another important building block of SNL’s irreverent comic sensibility.

Later cast members

The show’s changing ensemble has been the launching pad for countless performers who have become major television and motion picture stars, most of them developing recurring signature characters or impersonations on SNL. The following list only scratches the surface of those who have made their name on the show: Bill Murray, Al Franken, Don Novello (“Father Guido Sarducci”), Eddie Murphy, Julia Louis-Dreyfus, Robert Downey, Jr., Dennis Miller, Dana Carvey, Phil Hartman, Chris Rock, David Spade, Chris Farley, Sarah Silverman, Mike Myers, Adam Sandler, Molly Shannon, Will Ferrell, Jimmy Fallon, Tina Fey, Amy Poehler, Andy Samberg, Fred Armisen, Jason Sudeikis, Kristen Wiig, Kate McKinnon, and Bowen Yang. The anchor chair of SNL’s fake news segment, “Weekend Update,” holds special prominence and has been notably occupied by Chase, Curtin, Akroyd, Murray, Miller, Norm Macdonald, Fey, Seth Meyers, Colin Jost, and Michael Che, among others.

Guest hosts and musical guests

The guest hosts tend to be celebrities on the rise or actors, including former cast members, with a new movie to publicize. There are a number of performers who have long been associated with SNL as guest hosts, including Steve Martin, Paul Simon, John Goodman, Christopher Walken, and Alec Baldwin.

From its start, the program also has been an essential gig for musicians, both for up-and-coming groups and singers as well as for some of the biggest names in the music industry, an eclectic array that has included Elvis Costello, Nirvana, the Rolling Stones, Garth Brooks, Radiohead, Run-D.M.C., U2, Britney Spears, Beyoncé, Kanye West, and Taylor Swift.
