Did Rock N Roll and Grunge die, because WHITES turned to HIP HOP?

Even though HIP HOP is starting to get corny and annoying and is dying. What ever happened to Rock N Roll and Grunge? I remember growing up in the 90's, all you heard was Bon Jovi this, Bon Jovi that. Def Leopard this, Def Leopard that or Nirvana this. Whites hated HIP HOP back in the 1980's and 1990's. They thought it is was garbage. Personally I rather listen to the Rock n Roll and Grudge now, than the B.S Hip Hop, they are coming out with now. Did Whites turn to Hip Hop? What made Grunge and Rock N Roll fadeaway quick? Was it the death of Kurt Kobain?
