It exploded, It is applied in many areas such as camera focussing, controllers of all types, etc. Just do a simple Google search to see the vast variety of applications that have been suggested or implemented already. Having said that, I must admit that I am still a skeptic. At a conference, I once discussed with a control systems expert the reason why fuzzy controllers are used and sometimes have performance that exceeds that of ordinary controllers. His claim (and I have no independent verification of this) is that fuzzy controllers tend to monitor the system very closely---more closely that typical classical controllers---and so use better estimates of the "state". Their use of better information results in better performance, or so he said.
