It set a record for “most number of same-product television endorsements within 24 hours” on February 28, 2012, after 90 group members appeared in 90 different commercials aired in the Kanto, Kansai and Tokai regions of Japan.

Yasushi Akimoto criated a idol girlgroup with own teather with the purpose to perfoming daily (unlike pop groups performing occasional concerts and seen on television). They located on the 8th floor of Don Quijote (Akihabara, Tokyo). AKB48 included 134 members on December, 2018, with the concept of “Idols you can meet”.
Akimoto has expanded the AKB48 concept to several sister groups.

AKB48 was intended to have 16 members on each of three teams, forming a total membership of 48, but its membership has varied over time and has exceeded 120 people.
New members are called Kenkyuusei’s, who are understudies for the group,performing occasionally in the theater as a team.

AKB48’s line up has frequently changed due to departures, admissions, team rotations, and transfers between AKB48 and its various sister groups.
On November 10, 2018, the group consists of 134 members, divided among several teams: Team A with 28 members, Team K with 27 members, Team B with 29 members, and Team 4 with 26 members, Team 8 with 45 members, the last of which have all members serving concurrently with other AKB48 teams.

AKB48 released its first independent-label single, “Sakura no Hanabiratachi”, in February 2006. On June 7 AKB48 released its second independent single, “Skirt, Hirari”, and they had an television appearance two days later.

The group’s style has been characterized as “bubblegum pop and synchronised dancing”, appealing to prepubescent girls and older males who purchase the group’s merchandise.
AKB48 and sister groups boost their record sales by a variety of marketing strategies. The main track for each single is recorded by a team of a selection called “Senbatsu” with popular members from AKB48’s teams and sister groups, with one of the girls selected as the center performer of the single, called Center.
