Girls' Generation (Hangul: 소녀시대; Hanja: 少女時代) is a South Korean nine-member girl group formed by SM Entertainment in 2007. Its members include (in order of official announcement) Yoona, Tiffany, Yuri, Hyoyeon, Sooyoung, Seohyun, Taeyeon (the leader) , Jessica, and Sunny. International Girls' Generation fans usually refer to the group as SNSD, the acronym of the group's Korean name So Nyeo Shi Dae. Many of the members had already pursued entertainment careers before the group's debut through music videos, commercials, and others. Their official fanclub is known as S♡NE (소원, soweon), named after a song from their debut single. Their official ballon color is pastel rose pink and while other idols have round shaped balloons, Girls' Generation balloons are heart shaped to match their fanclub name.
The group has sold over 100,000 copies each of their first three albums, a first for female groups in South Korea.
