The Spice Girls are a British girl group formed in 1994, consisting of Melanie Brown, also known as Mel B; Melanie Chisholm, or Melanie C; Emma Bunton; Geri Halliwell; and Victoria Beckham. With their "girl power" mantra, they redefined the girl-group concept by targeting a young female fanbase. They led the teen pop resurgence of the 1990s, were a major part of the Cool Britannia era, and became pop culture icons of the decade. The group formed through auditions held by managers Bob and Chris Herbert, who wanted to create a girl group to compete with the British boy bands popular at the time. They signed to Virgin Records and released their debut single "Wannabe" in 1996, which reached number one on the charts of 37 countries. Their debut album, Spice, sold more than 23 million copies worldwide, becoming the best-selling album by a female group in history. The follow-up, Spiceworld, sold more than 14 million copies worldwide.
