T-ara was formed by the record label Mnet Media, which is now known as Stone Music Entertainment. The original members of T-ara were Jiae, Jiwon, Eunjung, Hyomin and Jiyeon. They trained together for three years before their debut. The group's name is based on the word "tiara". The idea for the name was that they would be "queens of the music industry". Their first song came before their official debut as a group. It was "Joheun Saram" for the soundtrack of the "Cinderella Man" television show. One month before their official debut, Mnet Media changed some of the members of the group. Jiae and Jiwon left T-ara in early June 2009, and were replaced by Boram, Soyeon, and Qri. Then in early July 2009, T-ara was moved from Mnet Media to Core Contents Media. Core Contents Media is a subsidiary of Mnet Media, and is now known as MBK Entertainment.
