13. AKB48 – 30.77 Million Records Sold
AKB48 (read “A.K.B. Forty-eight”) is a Japanese idol girl group. As of November 2013, the group has 89 members, whose ages range from early teens to mid-20s. AKB48 is named after Akihabara (Akiba for short), the area in Tokyo where the group’s theater is located. The idea of AKB48’s producer Yasushi Akimoto was to create a girl group that, unlike a regular pop group that gives occasional concerts and that is mostly seen on television, would have its own theater and perform there on a daily basis; the fans would always be able to go and see the girls live.
