The Spice Girls are an English girl group formed in 1994, consisting of Melanie Brown, also known as Mel B ("Scary Spice"); Melanie Chisholm, or Melanie C ("Sporty Spice"); Emma Bunton ("Baby Spice"); Geri Halliwell ("Ginger Spice"); and Victoria Beckham ("Posh Spice"). 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 Spice Girls formed through auditions held with the intent to create a girl group to compete with the British boy bands popular at the time. They quickly left the managers and took creative control over their sound and image. The Spice Girls 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 (1996), sold more than 23 million copies worldwide, becoming the best-selling album by a female group in history. It produced three more number-one singles: "Say You'll Be There", "2 Become 1" and "Who Do You Think You Are"/"Mama". Their second album Spiceworld (1997) was another global success, selling more than 14 million copies worldwide. They achieved three number-one singles from the album with: "Spice Up Your Life", "Too Much" and "Viva Forever". Both albums encapsulated the group's dance-pop style and message of female empowerment, with vocal and songwriting contributions shared equally by the members. In 1997 the Spice Girls made their live debut concert tour and released a feature film, Spice World, both to commercial success. In 1998, the group embarked on the Spiceworld Tour, which was attended by an estimated 2.1 million people worldwide, becoming the highest-grossing concert tour by a female group, grossing an estimated $220–250 million in ticket sales. Halliwell left the Spice Girls mid-tour in May 1998. Following a number-one single with "Goodbye" (1998) and a successful 1999 concert tour, the Spice Girls released their R&B-influenced third album Forever (2000). It featured their ninth number one single with "Holler"/"Let Love Lead the Way", setting a record for most UK number ones by a girl group of all time. At the end of 2000, the Spice Girls entered a hiatus to concentrate on their solo careers. Since then, they reunited for two concert tours; the Return of the Spice Girls (2007–2008) as a five-piece
