In the past few years, mixed martial arts has enjoyed remarkable commercial success. Some fans imagine that its popularity is a result of its vast technical superiority over traditional martial arts styles. But neither MMA techniques nor training methods are particularly innovative; much of what you see in the competition ring was pioneered decades or even centuries ago.
The recent success of the MMA product is best explained with a sociological model, not a technical one; and this model predicts an inevitable fall from grace. MMA will decay, like every style before it, into a traditional martial art.
