NSYNC (, ; also stylized as *NSYNC or 'N Sync) was an American boy band formed in Orlando, Florida, in 1996 and launched in Germany by BMG Ariola Munich. NSYNC consisted of Justin Timberlake, JC Chasez, Chris Kirkpatrick, Joey Fatone, and Lance Bass. After heavily publicized legal battles with their former manager Lou Pearlman and former record label Bertelsmann Music Group, the group's second album, No Strings Attached (2000), sold over one million copies in one day and 2.42 million copies in one week, which was a record for over fifteen years. Among the group's singles, "I Want You Back", "Bye Bye Bye", "This I Promise You", "Girlfriend", "Pop" and "It's Gonna Be Me" reached the top 10 in several international charts, with the last being a US Billboard Hot 100 number one. In addition to a host of Grammy Award nominations, NSYNC has performed at the World Series, the Super Bowl and the Olympic Games, and sang or recorded with Elton John, Stevie Wonder, Michael Jackson, Janet Jackson, Britney Spears, Phil Collins, Celine Dion, Aerosmith, Nelly, Left Eye, Mary J. Blige, country music supergroup Alabama, and Gloria Estefan.
NSYNC last recorded new material in 2002. The band completed five nationwide concert tours and has sold between 50 and 70 million records, becoming the fifth-best-selling boy band in history. Rolling Stone recognized their instant success as one of the Top 25 Teen Idol Breakout Moments of all time. Justin Timberlake went on to become one of the world's best-selling music artists, with more than 56 million records sold throughout his solo career.
