During the 1990s, some European managers created their own boy band acts, beginning with Nigel Martin-Smith's Take That and East 17, which competed with Louis Walsh's Irish bands Westlife and Boyzone. In 1996, the male saturated market was turned on its head by one of the most successful and influential pop acts of the decade, the Spice Girls. The group achieve nine number 1 singles in the UK and US, including "Wannabe", "2 Become 1" and "Spice Up Your Life". The group, unlike their British boy band predecessors, manage to break America and achieve the best-selling album of 1997 in the USA. More Girl Groups begin to emerge such as All Saints, who had five number 1 hits in the UK and two multi-platinum albums. By the end of the century the grip of boy bands on the charts was faltering, but proved the basis for solo careers like that of Robbie Williams, formerly of Take That, who achieved six number one singles in the UK between 1998 and 2004. Additional popular European teen pop acts of the 1990s included Ace of Base, Aqua and A*Teens.
