Freestyle skiing and the halfpipe.

Hot-dog skiing

Greg DiTrinco's 2024 article in Skiing History, the magazine of the International Skiing History Association, describes a 1971 freestyle contest, the "Hot Dog Competition: National Championships of Exhibition Skiing", in New Hampshire. It says Tom Corcoran organised it after a challenge from the Skiing magazine editor Doug Pfeiffer in late 1970, and that the same New Hampshire area had opened the first US freestyle instruction programme in 1969.

Two other accounts push the start earlier or frame it more broadly, and both rest on search summaries only, so they are unconfirmed:

• a CBC history is reported to say competitive freestyle began in the 1960s and that the first freestyle meet is "believed" to have been held in New Hampshire in 1966;
• the New England Ski Museum is reported to say freestyle and snowboarding, two new American forms, appeared in the 1970s.

FIS recognition, 1979

FIS's page on its 32nd International Ski Congress, held in Nice on 18 and 19 May 1979 with 104 delegates from 41 countries, records the decision "Recognition of Acrobatic Skiing and Skiing on Grass". FIS's word in 1979 was "acrobatic"; secondary sources, including Wikipedia, describe this as FIS recognising freestyle in 1979. The FIS Statutes of 2026 now list the discipline as Freestyle and Freeski.

Freestyle at the Olympics

The first Olympic steps rest mainly on search summaries of Wikipedia and an IOC news story, because the IOC's website timed out whenever it was tried. On that basis, and unconfirmed: freestyle was a demonstration sport at Calgary 1988, with moguls, aerials and ballet; moguls became the first freestyle medal event at Albertville 1992, won by Edgar Grospiron of France; and aerials joined at Lillehammer 1994. The Wikipedia article on freestyle skiing, when it was read for this site, named only "acroski" for the Calgary demonstration.

For ski cross and freestyle big air, secondary sources give Olympic debuts in 2010 and 2022; no IOC or FIS page dating either was read, so those years are unconfirmed.

The Sochi 2014 additions are better documented, in two IOC Executive Board decisions of 2011 as the press reported them:

• The Moscow Times reported on 6 April 2011 that the Board, meeting in London, added men's and women's ski halfpipe, together with women's ski jumping, citing universality, gender equity and youth appeal, and put off a decision on slopestyle.
• The South African Government News Agency reported on 5 July 2011 that the Board then added ski slopestyle, along with snowboard slopestyle and snowboard parallel special slalom.

FIS listed 15 freestyle medal events at Milano Cortina 2026 and named dual moguls among the Games' innovations. For the French Alps 2030, The Sports Examiner, relaying the IOC's announcement, reported on 7 July 2026 that freeride skiing and a freestyle ski cross mixed team event were added.

The halfpipe

A natural pipe in Tahoe

Where the halfpipe began is disputed, and every version rests on search summaries:

• Summaries of an Anchorage Daily News feature and of Wikipedia say two Lake Tahoe riders began using a natural halfpipe on land near Tahoe City in 1979, the "Tahoe City Pipe".
• Whitelines, also seen only in a summary, tells it differently: the pipe was formed after a dumper truck cut a small valley, in the winter after a 1981 contest.

The first contest and the first built pipe

The Summit Daily News says the 1983 World Snowboarding Championships in California, staged by Tom Sims, were the first snowboard halfpipe contest, and that the Burton team threatened to boycott them. It says a Colorado resort built a halfpipe when the World Championships moved there in 1986; this site does not name the resort. A Whitelines summary says the first purpose-built pipe-grooming machine, the Pipe Dragon, came in 1990 or 1991; that is unconfirmed.

The halfpipe at the Olympics

Snowboard halfpipe has been on the Olympic programme since Nagano 1998, according to The Canadian Encyclopedia, and ski halfpipe since Sochi 2014, following the April 2011 decision reported by The Moscow Times.

At a glance

The freestyle and freeski disciplines as FIS runs them today are on freestyle and freeski, and the snowboard side of the story on snowboarding joins the mountain.
