The history of extreme sports is still evolving. Some extreme sports combine the techniques and physical skills of two or more sports, often mainstream sports that were once considered extreme. One of the best examples of this sort of transition is found with sky surfing, which first became popular in the 1990s. The sport combines skydiving and snowboarding. Experienced parachutists perform acrobatic stunts on boards similar to snowboards. Individually, skydiving and snowboarding were once considered extreme. And snowboarding's own development owed much to the sports of skateboarding and surfing, which were considered nontraditional when they were first popularized in the 1960s.
There is no doubt that as new techniques are tried and experimented with, the history of extreme sports will include many new and daring innovations.
