The 2009 Freestyle World Championship in Fukushima,
Japan.
Freestyle skiing is an acrobatic form of skiing which is divided into a number of different disciplines. Freestyle skiing first began to be taken seriously in the 1960s and early 1970s. However, some people thought that this style of skiing was too dangerous and did not want it to be an Olympic sport. The free-form sport had few rules and was not without danger; knee injuries became a common case for professional freestylers.
