SES was the most famous girlgroup in the past, they are legends and the "textbook" for any other girlgroups. It took SM almost 10 years to made another girl group that is Girls Generation which become the "standard" of girlgroup. Thanks SM for creating SES and Girls Generation. Next year is the 10th year after the SNSD debuted, I hope SM will debut a girlgroup that can become another best girlgroup of the next kpop generation.
