There is a lot of talk on the internets about different mma organizations and assumptions that there should or could be only one dominating organization, similar to other sports.

However, that got me wondering how many professional boxing associations there are.

Wikipedia lists 27. Out of those 27, there are 4 major competitors to hold world championships. When looking at the potential future of mma promotions, this analogy seems a lot more relevant to mma organizations than NBA, NFL, NASCAR, etc. Competition between mma promotions could be around for a while.
