If you do not know, the UFC and K-1 have been working together.
Today I picked up the paper and there was an interview with Mr. Tanikawa who is the producer for K-1. In the interview Tanikawa said that FEG(basically sports agent branch of K-1) negotiated to loan Royce Gracie to the UFC. They negotiated who the opponent would be and the fight purse. Tanikawa said that that show(UFC 60) did 800,000 ppv buys, and he feels it was because of Royce. Tanikawa said that FEG would receive half of the ppv buy profits. Tanikawa said 3.2 billion yen was made(around 32 million dollars, 800,000 buys), so FEG gets 16 million dollars.
I was pretty surprised to read this news, as half is alot. I never thought much of the Gracie/Hughes fight, it didn't make sense to me as a fight(I thought Royce would lose easily), but it made alot of business sense. Especially for K-1.
