=== Ski ballet (Acroski) ===
{{Main|Ski ballet}}
Ski ballet, later renamed acroski (or "acro"), was a competitive discipline in the formative years of freestyle skiing. Competitors devised routines lasting 3 to 5 minutes and executed to music. The routines consisted of spins, jumps, and flips on a prepared flat course. For a short period of time (in the 1980s) there was also '''pair ballet''' competitions, a variation of ballet, where two people performed tricks that not only included spins, jumps and leg crossing but also lifts and sychronic movements and was similar to [[ice dancing]]. The routines were scored by judges who assessed the choreography, technical difficulty, and mastery of skills demonstrated by the competitors. Early innovators in the sport were American [[Jan Bucher]], Park Smalley, Swiss [[Conny Kissling]] and German [[Hermann Reitberger]]. The first skier who performed a one handed pole flip in a world cup competition was German [[Richard Schabl]] in the early 1980s. Acro ski was part of the demonstration at the [[1988 Winter Olympics]] in Calgary. The [[International Ski Federation]] ceased all formal competition of this event after 2000 because they focused on both aerials (1990) and moguls (1992) for making it an Olympic discipline.<ref>Johannes Knuth: Wie Olympia das Skiballett zerstörte.
