In 2011, these groups debuted as a K-Pop group and up until today, they are still intact and active. Some members of the groups left already to pursue other things but that did not stop remaining members to continue their promotions as a group.
Some groups who debuted with them that are now disbanded/inactive: Boyfriend, Dal Shabet, Sistar19, Stellar, and Troublemaker
