If someone talk about “No Body” or “Tell Me” music album, people will remember directly to famous girl band “Wonder Girls” from Korea but most of the people will not know more about other famous Korean Girl Bands in 50 years.
As from the source, “The Kim Sisters were arguably the first girl group in the history of Korean popular music. They debuted in their teens in the early 1950s, and were extremely popular among U.S. soldiers stationed in Korea. They played many instruments and danced, and enjoyed substantial success in the United States when they debuted there in 1959. After returning to Korea in 1970, they released a number of hit songs.” and the first girl ‘idol’ group in Korea would have been S.E.S.

S.E.S. enjoyed enormous popularity among men with their pretty faces, sweet voices and cute dance moves. They were the first to break the stereotype in the K-pop scene that girl groups do not sell. Their third album sold 780,000 copies, and S.E.S. remains the girl group that sold the most albums in K-pop history.
Next was Fin.K.L. who distinguished themselves from the upscale image of S.E.S. by making themselves look more approachable and eventually became their chief rival.
In 1997 came Baby V.O.X. and in 2001 Jewelry. Girls’ Generation debuted in 2007 and consists of nine multi-talented members who are fluent in English, Chinese and Japanese and are capable of singing, acting, and presenting.
The Wonder Girls, who also debuted in 2007, became famous before they had even made their official debut through a reality show on MTV Korea. The year 2009 has been the heyday of girl groups, with a huge number of such groups bursting onto the scene. 2NE1, Kara, After School and 4minute are some of the most recent additions in half of a century.
