Nike manufactures Jordan.
Jordan endorses his own damn shoes.
Basketball players no matter what music genre they're into will always buy J's. Coaches set Jordans as the 'team shoe' in high schools across the nation.
Young Joc saying "J's on my feet" in a song didn't make them the shoes they are today.
Sure hip-hop embraced Jordan's into their subculture, but to give hip hop all the credit is absurd.
Without Nike, Jordan's wouldn't exist (at least with the swoosh logo on them) and very understandably wouldn't be the same shoe it is today. So until Jermaine Dupri and Jay Z buy majority stock in Nike and start cutting M.J. fat checks, I'm going to say Nike and Michael Jordan made Jordan's what they are. A hot product will sell to anybody, even if one subculture doesn't like it.
Hip Hop isn't bigger than a free market economy full of easily impressionable consumers.
