when did freestyle skiing become an olympic sport
Freestyle skiing was a demonstration sport at the 1988 Winter Olympics, with moguls, aerials, and ballet events. Moguls became an official medal sport at the 1992 games, while aerials and ballet were still demonstration events. At the 1994 games, aerials also became an official medal event and the ski ballet competition was dropped. For the 2010 Winter Olympics, ski cross was added to the program while for the 2014 Winter Olympics half-pipe and slopestyle were added.
