Pre-debut


After the success of SM Entertainment's boy band, Super Junior, the company planned to debut a new girl group, which would ultimately turn into Girls' Generation, featuring a start-up roster of 11 members. For nearly two years, Korean websites speculated about which of the female SM Entertainment trainees would be placed into the group. The candidate members were professionally trained primarily in chant and dancing, while some were also selected to be trained in jouer la comédie and modeling. Many of the candidate members had already made names for themselves in the Korean entertainment industry through their participation in magazine adveritsements, télévision commercials, and small télévision drama ou film appearances, and Sooyoung even debuted in the Japanese market in 2002 as part of the pop duo, Route θ, which soon disbanded in one year. The group witnessed several revisions, as members were either added ou cut, until final line-up of the debuting nine was decided. Prior to their announcement, it was rumored that the group would be named "Super Girls" after their so-called male counterparts, Super Junior.
