input: The Roots' original lineup included Tariq "Black Thought" Trotter (MC) and Ahmir "Questlove" Thompson (drums), classmates at the Philadelphia High School for Creative and Performing Arts. As they began to play at school and on local streets, they added bassist Josh "The Rubberband" Abrams, who went on to form the jazz group The Josh Abrams Quartet. They later added another MC, Malik Abdul Basit-Smart ("Malik B.") and Leonard Nelson "Hub" Hubbard (bass), and Scott Storch (keyboards). Kenyatta "Kid Crumbs" Warren (MC) was in the band for Organix, the Roots' first album release. Another MC, Dice Raw, joined the band in cameo appearances on later albums. The band filled Storch's position with Kamal Gray (keyboards), who continues in that capacity. Kamal Gray did not play with the Roots on Late Night With Jimmy Fallon between April or May and early September 2012. His absence was not publicly explained, however on the September 17, 2012 (NBC's 'Late Night' 700th) episode, Gray returned to the group. Beatboxer Rahzel was a band member from 1995 to 1999. Alongside Rahzel was turntablist/vocalist Scratch, who also DJ'd in live concerts. However Scratch left abruptly in 2003. Malik B. left the group in 1999 due to personal reasons but continued to record, making occasional cameos on some albums. Guitarist Ben Kenney, had a brief stint with the group and contributed to the Phrenology album, but left to join Incubus as bassist. Percussionist Frank Knuckles joined the lineup in 2002 and guitarist Kirk "Captain Kirk" Douglas replaced Kenney. Vocalist Martin Luther toured with the Roots in 2003 and 2004 and contributed to the Tipping Point album. The group announced in August 2007 that its longtime bassist Leonard Hubbard was leaving. Owen Biddle was the band's bassist in 2007-2011. The band announced on August 25, 2011 that Owen Biddle left the band, replaced by Mark Kelley. On The Tonight Show Starring Jimmy Fallon, James Poyser plays additional keyboards. Because most of the band members hail from Philadelphia and its surrounding area, they showed their support for the Phillies during the 2009 World Series against the Yankees, displaying Phillies memorabilia when performing on Late Night with Jimmy Fallon. On the episode which aired the day after the Yankees clinched the title, Questlove stated "No comment!" on the show's intro (when he usually states the episode number), and had a Yankees logo purposely displayed upside-down on his drumset. In 2010, the group showed support for the Flyers during their run to the Stanley Cup Final by having the team logo on their drumset, and again in 2014 when the Flyers faced the New York Rangers in the first round of the playoffs on The Tonight Show Starring Jimmy Fallon. In April 2017, Frank Knuckles left the Roots due to family issues, and has not appeared on The Tonight Show since then. Later in August 2017, Knuckles sued Questlove, Black Thought and the band manager Shawn Gee over unpaid royalties. In June 2017, Questlove announced in an interview that producer and performer Stro Elliot is an official member of the Roots.

input: NBC became the first large United States network to broadcast the same show every weekday during prime time since ABC's Who Wants to Be a Millionaire? marathons in 1999 and only the second since DuMont aired Captain Video and His Video Rangers from 1949 to 1955. More recently, the upstart MyNetwork TV had attempted, upon its launch in 2006, to air the same telenovelas every night of the week, a programming strategy that proved to be very unsuccessful. NBC's executives called the decision "a transformational moment in the history of broadcasting" and "in effect, launching five shows." An industry observer said that Leno, "in all my years, is the biggest risk a network has ever taken." According to former NBC president Fred Silverman, "If the Leno Show works, it will be the most significant thing to happen in broadcast television in the last decade." Although NBC had not developed a new hit show at 10 pm in years, industry executives criticized the network for abandoning a history of airing quality dramas at that hour such as Hill Street Blues, St. Elsewhere, and ER, which made NBC "the gold standard for sophisticated programming . . . the No. 1 network for affluent and well-educated young viewers" during the 1980s and 1990s. In addition, critics predicted that the decision would hurt NBC by undermining a reputation built on successful scripted shows. Other networks believed NBC's decision created an opportunity, and planned their 2009-2010 schedules accordingly. For example, the show competed with The Mentalist, CSI: Miami, CSI: NY, and Numb3rs, four of television's most popular series, on CBS (the first of those four series was moved to 10:00 PM to directly compete with Leno's show, and significantly improved the ratings for that timeslot compared to its predecessor). Leno was also not easily sold overseas. The January 29, 2010 issue of Entertainment Weekly listed the show at the top of a list of the 50 Biggest Bombs in television history. The comment made by the network executives about "launching five shows" was ultimately transformed into the joke that its removal was like "cancelling five shows". TV Guide similarly listed the show as the biggest blunder in television history in its November 1, 2010 edition.
