It was started when Shogakukan, which was focused mainly on educational magazines and other related publishing at the time, decided to spin off a company (Shueisha) to produce entertainment (especially manga) magazines. Eventually, Shogakukan moved into the entertainment business as well, and became a rival of Shueisha, and the group was formed to help each one grow. The headquarters buildings for Shogakukan and Shueisha are right next to each other.
