The group is often referred to as Soshi or SNSD by international fans, the first of which is an abbreviation and the second an acronym of the group’s Korean name So Nyeo Shi Dae. They are known as Shàon? Shídài in China and Taiwan, Siu Nui Si Doi in Hong Kong and as Sh?jo Jidai in Japan.

SNSD officially debuted in August 2007 with their single Into the New World or Dasi Mannan Segye in  Korean. The group released their first self-titled full album in November 2007 with the lead single Girls’ Generation, a remake of Lee Seung-cheol’s 1989 hit. The album also included the group’s first single Into the New World, Perfect For You retitled as Honey, and 8 other tracks by the group. In early 2008, Girls’ Generation began promoting their second single from the album, Kissing You, which won the group their first k-chart win after getting the number one position on the KBS Music Bank February chart.

In March 2008, the album was re-packaged, re-released and re-titled Baby Baby. A third single, Baby Baby, was used to promote the album. During the group’s promotions, members Jessica, Tiffany and Seohyun were also featured on a mini-album released by Roommate, a one-man band from Purple Communication. The mini-album was titled Roommate: Emotional Band Aid, and was released on December 1, 2008. The 3rd track from the mini-album was performed by the 3 Girls’ Generation members and is titled Oppa Nappa. The track was digitally released before the album was, coming out in April 2008 and topping several charts.
On December 26, 2008, the pink unicorn posters of the Girls’ Generation members wearing sporting simple white shirts, jeans and roller-skates were posted up in various locations around Seoul. The posters were met with such popularity that SM Entertainment’s phone-lines were blocked up by callers asking whether the posters were for sale and the company was forced to ask fans to stop taking the posters down for personal use. Three days later on December 29, the group’s management confirmed that the posters were indeed teaser posters and that the group would soon release their first EP, The First Mini Album – Gee the following month in January 2009.
A teaser video was released in January 2009 and the first single Gee released soon after. Gee was a mega hit, topping Cyworld’s hourly music chart on the release day. The song also went #1 on all major digital music charts within two days. 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. The music video set a record on release, garnering 1 million views on GomTV in under a day. The music video became the first to reach “Diamond Track” status on GomTV after breaking the 5 million view mark on January 16. The music video now has over 36 millions views on Youtube, snatching the spot for the most viewed video in Korea.

After a short break, SM Entertainment announced that the group would be back with a new mini-album sporting a "Marine Girl" concept. The new single was to be titled Tell Me Your Wish (Genie); with the full mini album being released digitally on June 22, 2009. The track proved to be a success as it conquered various music sites like Melon, Dosirak, MNet, Bugs and it was No.1 on the weekly charts and SKT ringtone weekly charts of the first week of July. The mini-album sold an estimated 50,000+ copies in its first week after released (almost double the numbers from the first-week sales of Gee), an unusual feat for any Korean girl group.

SNSD kicked off 2010 with their second full length album Oh! in January 2010. The lead single Oh!, was digitally released on January 25 with the music video being released two days later. The song proved to be another big hit, topping various charts upon release.

'Oh!' also went on to win Music Bank's half-year K-chart, coming in at 2nd on Hanteo's first half album sales chart, and also winning the end-of-year K-chart, proving to be the most successful release of the year.
