The boy band phenomenon swept across the U.S. in the late '90s, causing Beatle-like mania among young pop fans. At the forefront of this hysteria were the Backstreet Boys. Melting the hearts of young girls everywhere, the Backstreet Boys achieved massive success with albums like Millennium and Black & Blue. Taking a three year hiatus after 2000, the band returned to the spotlight in 2005 and has since continued to release albums and tour. With worldwide sales reaching a staggering 130 million albums, the Backstreet Boys remain one of the best selling artists of all time.
