NSYNC (sometimes stylized as ★NSYNC) was an American boy band formed in Orlando, Florida in 1995 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 Sony BMG, the group's second album, No Strings Attached, sold over 1 million copies in one day and 2.42 million copies in one week. 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, Phil Collins, Celine Dion, Aerosmith, Britney Spears, Nelly, Left Eye, Mary J. Blige, and Gloria Estefan.

Although NSYNC announced the start of a "temporary hiatus" in spring 2002, the band has not recorded new material since. The group's official website was shut down in the summer of 2006, and in 2007, Lance Bass confirmed that the group has "definitely broken up." They have sold over 50 million albums during their career becoming the eighth-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.
