Though Girls' Generation had gained some attention with their 2007 debut album, it was not until 2009 that the group rose to stardom. On January 7, the group released their debut extended play (EP) "Gee", which has sold over 100,000 copies in South Korea. Its title track claimed the number-one position on KBS's "Music Bank" for a record-breaking nine consecutive weeks, becoming the longest-running number-one song on "Music Bank" until 2012, when Psy's "Gangnam Style" claimed the top spot for ten consecutive weeks. It was the best-selling single of 2009 in South Korea. The group's second EP, "Tell Me Your Wish (Genie)" () and its titular lead single were released in June 2009. The EP sold 50,000 copies within its first week in South Korea, and charted at number eight on the Taiwanese G-Music chart. In November 2009, S.M. Entertainment announced the group's first concert tour, Into The New World, whose tickets for the South Korean shows were sold out in three minutes. The tour visited Seoul in December 2009, Shanghai in April 2010, and Taipei in October 2010.
