Most recently, NBC named Fallon as the replacement for Conan O'Brien on Late Night with Conan O'Brien emanating out of New York City. The show, which will serve as a platform for comedy, music, and A-list talent to promote their upcoming projects, is being executive produced by Lorne Michaels and premiered on March 2, 2009. In the months leading up to the broadcast debut, Fallon produced video blogs that ran online nightly at 12:30 AM ET on NBC.com.
Fallon first garnered attention in 1998 when he joined the cast of Saturday Night Live and quickly became an audience favorite for his impressions of Jerry Seinfeld, John Travolta, and Adam Sandler, as well as spot-on musical impressions of Justin Timberlake, Jack White, and Enrique Iglesias. Fallon created many memorable recurring characters on Saturday Night Live, including Nick Burns, the sarcastic tech support representative, rowdy Boston teen Sully known for playing tonsil hockey with Denise, as played by Rachel Dratch, and the explosive Barry Gibb opposite Justin Timberlake in the Barry Gibb Talk Show. In 2000, Fallon became the co-anchor of the popular segment "Weekend Update" alongside Tina Fey.
Always a favorite among the MTV audience, Fallon co-hosted the 2001 MTV Movie Awards with Kirsten Dunst and then again while solo in 2005. He also hosted the MTV Video Music Awards in 2002. In 2005, Fallon participated in Cameron Diaz's MTV eco-friendly travel show Trippin', where he traveled to Africa to educate viewers about one of the world's most unique and fragile ecosystems. In summer of 2003, Fallon earned raves while guest hosting for David Letterman.
