Girls' Generation-TTS (also known as Girls' Generation-TaeTiSeo and TaeTiSeo) is the first official sub-group of South Korean girl group Girls' Generation, formed by S.M. Entertainment in 2012. The sub-group is composed of three Girls' Generation members, Taeyeon (leader), Tiffany, and Seohyun.
History
Prior to the group's announcement in April 2012, the three worked together as MCs for the Korean music show, Show! Music Core, where they had been permanent hosts since February that year, Tiffany had already served as a MC on the show since 2009.
On April 19, 2012, S.M. Entertainment officially announced the sub-unit, stating in their official press-release that the subunit's intention was to "grab the attention of fans with all aspects of music, performance, and fashion styles." Also hinting at the possibility of future subunits containing other members, elaborating, "by changing the members of the unit according to the music and concept of each new subunit album." The label also revealed the thought process behind naming the unit "Girls’ Generation–TTS"”. The name "TaeTiSeo" is made up of the first syllables of Taeyeon, Tiffany, and Seohyun. This name has the letters "T" and "S", which have distinct sounds, giving a strong vibe of the team and also lets the fans recognize the members instantly.
The subunit's work was noticeably different from previous work done by the group, with the focus shifting towards vocals, rather than the highly synchronized choreography the group is known for, as well as more unique fashion choices. Specifically, Tiffany, who dyed her hair red during the group's promotional period, and stated that the group's styling and fashion choices were each of the girls', adding that they were definitely "hands-on" during the entire process.
