The Backstreet Boys (sometimes referred to as BSB) are an American vocal harmony group, formed in Orlando, Florida in 1993. The group consists of A. J. McLean, Howie Dorough, Nick Carter, Kevin Richardson, and Brian Littrell. They rose to fame with their debut international album, Backstreet Boys (1996). After a two-year hiatus, they regrouped and released a comeback album Never Gone (2005). Richardson left the group after the conclusion of Never Gone Tour in 2006 to pursue other interests. The group then released two albums as a quartet: Unbreakable (2007) and This Is Us (2009). In April 2012, the group announced that Richardson had rejoined them permanently.

The Backstreet Boys have sold over 130 million records worldwide, making them the best-selling boy band in history, and one of the world's best-selling music artists. They are the first group since Sade to have their first seven albums reach the top 10 on the Billboard 200. They also received a star on the Hollywood Walk of Fame on April 22, 2013.
