Their biggest fight was actually with Fedor vs Matt Lindland in Russia. Bodog and M-1 co-promotion. He certainly had the resources, but everybody should know by now it's a losing venture. Interesting enough Pro-elite is back. I think the small shops isolated to certain states or provinces with a loyal fan base will do well. Second tiered shows have proven they can not survive; Affliction, SF, Dream, etc. If they don't fold then they just get bought out. But for small shows it's not really worth it for them to buy em out cuz they don't have any assets.
Come to think it the UFC has completely taken over a market share in such a short time span which is amazing. Look at Coke and Pepsi...they're still battling after half a century...haha.
