Snowboarding is a recreational activity and olympic sport that involves descending a slope that is covered with snow while standing on a snowboard attached to a rider’s feet. The development of snowboarding was inspired by skateboarding, sledding, surfing and skiing. It was developed in the United States in the 1960s and became a Winter Olympic Sport in 1998. Its popularity (as measured by equipment sales) in the United States peaked in 2007 and has been in a decline since. Since snowboarding’s inception as an established winter sport, it has developed various styles, each with its own specialized equipment and technique.
