with the progress of time there must have been many styles that have died out. today's rare style is tomorrow's relic or even forgotten style. maybe the popularity of MMA which pulls many practitioners to a small handful of styles is adding to this process. I have heard from a few TKD guys that their classes have got much smaller over the years and they attribute this to BJJ and the likes attracting people way from their. for me I have my doubts of the validity of this however that is what they say. Also we have the addition of RBSD style systems which give much more to the person seeking self defence than maybe many of the traditional styles can. so are styles continuing to die out? if so what styles are dying?
