They are the biggest South Korean and generally asian girl group. They became really succesful in Japan with their debut japanese album which sold 800,000 + there and with their sold out tour. As the korean pop wave is getting bigger and bigger all over the world the girls' label has managed to do concerts with all its artists (including Girls' Generation) at Bejin, Tokyo, Los Angeles (2 times), Shanghai, Paris (which the reception there was huge and had 2 sold out concerts!), more recent at New York (at madison squarre making them the first asian artists to perform there) and also a big kpop concert at Sydney. They released their first english song The Boys (the english version of the korean song from their 3rd korean album) and they released a maxi single on itunes and amazon worldwide. They never really promoted The Boys in the US. They achieve though 2 performances at David Letterman and Live with Kelly making the first korean artists to appear on national television. Their third album was also released in the US, Spain and France reaching #64 in Spain, #84 France, #17 US Heatseekers and #2 US world albums. Their latest subunit Taetiseo (combined by 3 of their members) released the mini album Twinkle reaching the top five in the US and spending almost three days in the top 10. Because of the digital sales, the album debuted at No. 126 on the US Billboard charts, making TaeTiSeo (or should I say, Girls’ Generation) the second Korean artist ever to chart on the Billboard 200 with a Korean album. Now they will release a new Japanese single and they will be preparing their first English album under Universal records and Jimmy Lovine.
