Mixed Martial Arts has done alot for the industry. But if you look at the "Kung Fu" haze of the 70's, Karate of the 80's, and Tae Kwon Do of the 90's, those actually gave rise to more people getting into Martial Arts, 10-30 years before Mixed Martial Arts was introduced in 1993. Personally, I think Mixed Martial Arts has done more damage to the industry then good. But that's just from my personal experience, personal witnessing, and personal involvement!!
