when did freestyle skiing become an olympic sport
Freestyle skiing at the Winter Olympics 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.[1]
Mixed curling The IOC did not approve the events for inclusion into the 2010 Winter Olympics,[1][2] but an attempt to include the mixed doubles in the following winter Olympiad succeeded, making its Olympic debut at the 2018 Winter Olympics.[3]
