Surfing originated in Hawaii as a sport called i'enalu, involving sliding on the surface of waves. It developed mainly in Hawaii, Australia, and California from the 1960s onward. Major championships include the ASP World Tour, which was first held in Australia in 1964. There are different types of surfboards used depending on wave conditions and personal style, such as longboards, fish, and mini-malibu boards. Some of the best professional surfers who have dominated the sport include Kelly Slater, Andy Irons, and Laird Hamilton.
