Spice Girls were the first major British pop music phenomenon of the mid-'90s to not have a debt to independent pop/rock. Instead, the all-female quintet derived from the dance-pop tradition that made Take That the most popular British group of the early '90s, but there was one crucial difference. Spice Girls used dance-pop as a musical base, but they infused the music with a fiercely independent, feminist stance that was equal parts Madonna, post-riot grrrl alternative rock feminism, and a co-opting of the good-times-all-the-time stance of England's new lad culture. Their proud, all-girl image and catchy dance-pop appealed to younger listeners, while their colorful, sexy personalities and sense of humor appealed to older music fans, making Spice Girls a cross-generational success. The group also became chart-toppers throughout Europe in 1996, before concentrating in America in early 1997.

After years of persistent rumors of a reunion -- peaking heavily yet never materializing for Bob Geldolf's 2005 charity event Live 8 -- the Spice Girls announced in June 2007 that they would be reuniting for an eleven-concert tour beginning that December, which would be accompanied by a new greatest hits album and documentary.

In 2010, it was announced that the Spice Girls had joined forces with Simon Fuller to develop a musical based on their songs. Viva Forever: The Musical - penned by British comedienne Jennifer Saunders - was announced at a press conference in June 2012. After much speculation in the British press, the Spice Girls reformed once more for the closing ceremony of the London 2012 Olympics.
