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. Their self-titled debut album was successfully released to European countries in 1997, and later debuted in the US market with the single "I Want You Back".
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, sold over one million copies in one day and 2.42 million copies in one week, which was a record for over fifteen years. NSYNC's first two studio albums were both certified Diamond by the Recording Industry Association of America. Celebrity debuted with 1.8 million copies in its first week in the US. Singles such as "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.
