Girls' Generation (ì†Œë…€ì‹œëŒ€; å°‘å¥³æ™‚ä»£) is a nine-member South Korean girl group formed by SM Entertainment in 2007. The nine members are: Taeyeon (the leader), Jessica, Sunny, Tiffany, Hyoyeon, Yuri, Sooyoung, Yoona, and Seohyun . They are often referred to as SoShi (ì†Œì‹œ), or SNSD (mainly outside Korea), the first of which is an abbreviation and the second an acronym of the group's Korean name So Nyeo Shi Dae (or So Nyuh Shi Dae). In China, they are known as å°‘å¥³æ™‚ä»£ (ShÃ onÇš ShÃdÃ i; or Siu Nui Si Doi in Hong Kong) and in Japan as å°‘å¥³æ™‚ä»£ (ShÅjo Jidai).
The group has released two full albums, two mini-albums, and various singles. Their 2009 hit single "Gee" holds the record for being the longest running #1 song on KBS's Music Bank, having held the #1 chart ranking for 9 consecutive weeks. That year also saw the group winning various awards, including consecutive Artist of the Year (Daesang) awards at the Seoul Music Awards, Golden Disk Awards, Melon Music Awards, and the Korean Cultural Entertainment Awards.
The group began a foray into the Japanese music scene in late 2010, with the Japanese remakes of their 2009 Korean hits "Gee" and "Tell Me Your Wish (Genie)". In Japan they are under the label Nayutawave Records, a part of Universal Music. Late 2010, So Nyeo Shi Dae released the mini-album Hoot, which won various awards. In 2011, Girls' Generation entered the Japan's market with the double a-side single Mr.Taxi/Run Devil Run. Later, the group released a brand new japanese album, which contains twelve songs including hits like Bad Girl and The Great Escape.
The members were professionally trained primarily in singing, dancing and languages while a select few were also underwent further training in acting and modeling. Many of the members had already made appearances in magazine ads, television commercials, and small television appearances. For nearly two years, Korean websites speculated about which female SM Entertainment trainees would be placed into the group.
