Since the late 1990s, Korean talent agency and record label SM Entertainment has been holding annual auditions to scout new talents that complemented the success of pop groups H.O.T, S.E.S, and Shinhwa, all of which were created by SM founder Soo-Man Lee in the mid 1990s. Leeteuk and Eunhyuk were the first two members of the group to be recruited in 2000 under SM’s Starlight Casting System in Seoul.
In 2001, the company held their first overseas casting auditions and discovered Han Geng in Beijing, who was chosen among three thousand applicants. That same year, Yesung was discovered under Seoul’s casting system with his friend HeeChul. Sungmin and Donghae were also selected to be trainees after their appearance in an SM-sponsored contest. In 2002, Heechul and Kangin was recruited along with Kibum, who was discovered in Los Angeles. Siwon was casted in 2003 and Ryeowook in 2004, in which the latter was discovered through the Chinchin Youth Festival singing competition. In 2005, Shindong was selected.
Not long after boy band TVXQ’s debut in 2003, news about Lee’s unprecedented plans of forming another boy band quickly spread on the Internet. In early 2005,Lee confirmed the news and announced that an all-boy project group of twelve members would debut near the end of the year, promoting this singing group to be “The Gateway to Stardom of Asia.” Lee announced that that most members in this group were chosen because of their performing experiences as actors, MCs, models, and radio hosts prior debut. Heechul and Kibum were already established entertainers, and most of the other members had already made various kinds of appearances on television and media. Highly inspired by the rotational concept of Japan’s girl group Morning Musume, this group would also experience line-up changes, with new members replacing some selected members every year to keep the group constantly young and all-rounded. This concept was then newly introduced to the K-pop market.
Super Junior 05 made their pre-debut on the Korean channel Mnet on September 11, 2005. At the showcase, they performed various styles of hip hop dancing. The group danced to B2K’s “Take It To The Floor.” Han Geng, Eunhyuk, and Donghae also performed a separate dance away from the group, dancing to Usher’s “Caught Up.” However, the performance did not air on television until May 16, 2006 as a segment in the Super Junior Show, the group’s first television documentary.
