Girls' Generation debuted back in 2007 with "Into the New World," truly starting a whole new wave for both K-Pop and girl groups and making history.

Now, believe it or not, it has already been nine years since the girls have been active in K-Pop, taking over the industry by storm, and fans are celebrating via Twitter with "#9YearsWithSNSD," which is trending worldwide!

Happy 9th anniversary, Girls' Generation!  Congrats on your immensely successful career thus far, and we look forward to many more years to come!

I've been into this fandom since JHS.I can't believe 9 years has passed and my unconditional love toward them still the same #9YearsWithSNSD
