Idol bands (young boybands or girlbands) formed, inspired by Seo Taiji & Boys, to cater for a growing teenage audience. H.O.T. was one of the first idol boybands, debuting in 1996. Their success was followed by that of bands like Sechs Kies, S.E.S., Fin.K.L, NRG, Baby V.O.X., Diva, Shinhwa and g.o.d. The 1990s were also a successful period for underground music clubs and punk rock bands such as Crying Nut.
