Boyz II Men is an American R&B vocal group best known for emotional ballads and complex, intricate a cappella harmonies. Based on record sales, Boyz II Men are the most successful R&B group of all time, having sold more than 60 million albums worldwide. In the 1990s, Boyz II Men found fame on Motown Records as a quartet, but original member Michael McCary left the group in 2003 due to health issues. Currently the group is a trio signed to Decca Records, with members Nathan Morris, Wanya Morris, and Shawn Stockman. The group won four Grammy Awards in the 1990s, and the trio was nominated for two Grammies in 2009.
Boyz II Men formed at the Philadelphia High School for Creative and Performing Arts in 1988 as a quintet; however, original member Marc Nelson left the group before its first studio recording to pursue a solo career. In the 1990s, Boyz II Men gained international celebrity behind unprecedented success on the pop charts. The group's first single to reach number 1, 1992's "End of the Road", a phenomenal hit, reached the top of charts across the globe. "End of the Road" would set a new record for longevity, staying at number 1 on the Billboard Hot 100 for thirteen weeks, breaking a decades-old record held by Elvis Presley.
Boyz II Men would exceed even that record later in the decade with hits "I'll Make Love to You" and "One Sweet Day" (with Mariah Carey), which each exceeded records for the longest period of time a single remained at number 1. As of 2010, "One Sweet Day" still holds the all-time record with sixteen weeks at the top of the Hot 100. Although "On Bended Knee" did not exceed any records, it was still a very popular song that reached number 1 and made Boyz II Men the third artist (the other two are The Beatles and Elvis) to replace themselves at the number one rating of the Billboard Hot 100. Because of this, Boyz II Men are the only artists that have stayed at the number one spot cumulatively 50 times, just fourth behind Elvis Presley, The Beatles, and Mariah Carey. They also hold the numbers one, three and four spots for 3 of the longest running singles in music history with One Sweet Day, I'll Make Love To You and End of the Road. These achievements were enough to earn Boyz II Men recognition as Billboard Magazine's most successful musical group of the 1990s.
