Sport of sliding downhill over snow on a snowboard, a wide ski ridden in a surfing position. Derived from surfing and influenced also by skateboarding as well as skiing, snowboarding began to burgeon among young people in the U.S. in the mid-1980s. The first Olympic snowboarding competition was held in the 1998 Winter Games. The two main events are giant slalom (similar to Alpine giant slalom) and halfpipe, in which riders use a large, snow-covered trench (halfpipe) to repeatedly launch themselves into the air and perform various acrobatic feats.
