AKB48 is a Japanese idol girl group named after the Akihabara area of Tokyo, where the group's theater is located, and its original roster of 48 members. As of August 2014, the group has expanded to include 140 members aged from their early teens to their mid-20s. AKB48's producer, Yasushi Akimoto, wanted to form a girl group with its own theater and performing daily so fans could always see them live. This "idols you can meet" concept includes teams which can rotate performances and perform simultaneously at several events and "handshake" events, where fans can meet group members. Akimoto has expanded the AKB48 concept to several sister groups in Japan, China and Indonesia.
The group is one of the highest-earning musical performers in Japan, with 2013 sales of over $128 million, and has been characterized as a social phenomenon. As of March 2014 the group has sold over 30 million records, including over 28.78 million singles as of May 2014, the second-highest musical act in Japan in the number of singles sold and the highest by a girl group. ...more on Wikipedia
