”In the United States, the 1960s were a time of revolution, of young people challenging authority and demanding change. Freestyle skiing began in that decade, when social change and freedom of expression led to new and exciting skiing techniques. Originally a mix of alpine skiing and acrobatics, the first freestyle skiing competition was held in Attitash, New Hampshire, in 1966.
A relative newcomer to the Olympic Winter Games program, freestyle moguls became an Olympic medal discipline in 1992, at the Games in Albertville, Frankrijk. Freestyle aerials were added for the Lillehammer 1994 Olympische Winterspelen. Making its Olympic Winter Games debut in 2010, ski cross, an event within freestyle skiing, is based on a simple concept: first across the finish line wins.”
