Skeleton is one of the Olympic sport disciplines contested at the Winter Olympic Games.
 It was introduced at the 1928 Winter Olympics in St. Moritz – the birthplace of skeleton – in the form of a men's event contested over four runs.
 Dropped from the 1932 and 1936 Winter Olympics program, skeleton returned in 1948, when St. Moritz hosted again the Winter Olympics, but was discarded from the following Games in Oslo.
 After 54 years of absence from the Olympic program, skeleton was reinstated as an official medal sport at the 2002 Winter Olympics in Salt Lake City, featuring individual events for men and women.
For the Summer and Winter Olympics, there are 27 venues that have been or will be used for figure skating.
 This is one of two sports in the Winter Olympics to debut in the Summer Olympics with ice hockey being the other.
 The first venue for the event took place during the 1908 Games was held indoors.
 Twelve years later, the venue joined ice hockey as another Winter Olympic sport in the Summer Olympics.
 For the first two Winter Olympics, figure skating was held outdoors.
 With figure skating being held outdoors, there were weather concerns with thawing for the first two Winter Games.
 A suggestion by International Olympic Committee President Count Henri de Baillet-Latour to 1932 Olympic Organizing Committee President Godfrey Dewey in September 1930 led Dewey to create the first indoor arena for the Winter Olympics.
 For the 1936 Games, the venue was covered partially.
 Following World War II, the 1948 venue became the first venue to be used twice at the Winter Olympics since it had been used twenty years earlier.
 Figure skating's final competition that took place outdoors was in 1956 though that venue has since had a roof added to it.
 Since 1960, all figure skating competitions have taken place indoors.
 Three National Hockey League (NHL) venues have hosted Olympic figure skating competitions: the 1988 (both venues) and the 2010 though the NHL Vancouver Canucks moved out of the 2010 venue following the 1994–95 season.
 The 2002 venue was a National Basketball Association (NBA) venue which meant the Utah Jazz was on a road trip during the 2002 Games.
Snowboarding is a sport at the Winter Olympic Games.
 It was first included in the 1998 Winter Olympics in Nagano, Japan.
 Snowboarding was one of five new sports or disciplines added to the Winter Olympic program between 1992 and 2002, and was the only one not to have been a previous medal or demonstration event.
 In 1998, four events, two for men and two for women, were held in two specialities: the giant slalom, a downhill event similar to giant slalom skiing; and the half-pipe, in which competitors perform tricks while going from one side of a semi-circular ditch to the other.
 Canadian Ross Rebagliati won the men's giant slalom and became the first athlete to win a gold medal in snowboarding.
 Rebagliati was briefly stripped of his medal by the International Olympic Committee (IOC) after testing positive for marijuana.
 However, the IOC's decision was reverted following an appeal from the Canadian Olympic Association.
 For the 2002 Winter Olympics, giant slalom was expanded to add head-to-head racing and was renamed parallel giant slalom.
 In 2006, a third event, the snowboard cross, was held for the first time.
 In this event, competitors race against each other down a course with jumps, beams and other obstacles.
 On July 11, 2011, the International Olympic Committee's Executive Board approved the addition of Ski and Snowboard Slopestyle to the Winter Olympics roster of events, effective in 2014.
 The decision was announced via press conference from the IOC's meeting in Durban, South Africa.
 A fifth event, parallel slalom, was added be in 2014.
Freestyle skiing is one of the six skiing disciplines contested at the Winter Olympic Games, and one of the youngest.
 In 1924, the first Winter Olympics featured Nordic skiing disciplines (cross-country skiing, ski jumping, and Nordic combined), while alpine skiing was first contested in 1936.
 Only at the 1992 Winter Olympics, in Albertville, France, were freestyle skiing events first held as official medal events.
 Before that, freestyle skiing was contested at the 1988 Winter Olympics as a demonstration sport, consisting of events for both men and women in three variants: moguls, aerials and ski ballet.
 In Albertville, moguls was the first-ever official freestyle skiing medal event; aerials and ski ballet were also held but still as demonstration events.
 The growing popularity of aerials convinced the International Olympic Committee (IOC) to add this freestyle discipline to the 1994 Winter Olympics official program.
 Moguls and aerials have thus been contested at every Winter Games since.
 Ski cross inclusion in the Winter Olympics program was approved at an IOC Executive Board meeting in November 2006, and the first events were held at the 2010 Winter Olympics.
Kati Winkler (born 16 January 1974) is a German former competitive ice dancer.
 With partner René Lohse, she is the 2004 World bronze medalist and a six-time German national champion.
 They competed at two Winter Olympics, in 1998 and 2002.
Snowboarding is a sport that has been contested at the Winter Olympic Games since the 1998 Winter Olympics in Nagano, Japan.
 Snowboarding was one of five new sports or disciplines added to the Winter Olympic programme between 1992 and 2002, and was the only one not to have been a previous medal or demonstration event.
 In 1998, four events, two for men and two for women, were held in two specialities: the giant slalom, a downhill event similar to giant slalom skiing; and the half-pipe, in which competitors perform tricks while going from one side of a semi-circular ditch to the other.

 Rebagliati was briefly stripped of his medal by the International Olympic Committee (IOC) after testing positive for marijuana.
 However, the IOC's decision was reverted following an appeal from the Canadian Olympic Association.
 For the 2002 Winter Olympics, the giant slalom was dropped in favour of the parallel giant slalom, an event that involves head-to-head racing.
 In 2006, a third event, the snowboard cross, was held for the first time.
 In this event, competitors race against each other down a course with jumps, beams and other obstacles.
Ice dancing is a discipline of figure skating that draws from ballroom dancing.
 It joined the World Figure Skating Championships in 1952, and became a Winter Olympic Games medal sport in 1976.
René Lohse, married Sachtler-Lohse (born 23 September 1973) is a German former competitive ice dancer.
 With partner Kati Winkler, he is the 2004 World bronze medalist and a six-time German national champion.
 They competed at two Winter Olympics, in 1998 and 2002.
Hannah Campbell-Pegg (born 24 June 1982 in Sydney) is an Australian Luge athlete who has competed since 2004.
 Competing in two Winter Olympics, she finished 23rd in the women's singles event twice (2006, 2010.
 Campbell-Pegg qualified with little experience in the sport for the 2006 Winter Olympic Games becoming Australia's 3rd athlete to ever do so behind Diane Ogle (1992 Winter Olympic Games Albertville, France) and Roger White (1994 Winter Olympic Games Lillehammer, Norway).
Ice hockey is a sport that is contested at the Winter Olympic Games.
 A men's ice hockey tournament has been held every Winter Olympics (starting in 1924); an ice hockey tournament was also held at the 1920 Summer Olympics.
 From 1920 to 1968, the Olympics also acted as the Ice Hockey World Championships, and the two events occurred concurrently.
 From 1920 until 1984, only amateur athletes were allowed to compete in the tournament, and players from the National Hockey League (NHL) were not allowed to compete.
 In 1970, after a disagreement over the definition of amateur players, Canada withdrew from the tournament and did not send a team to the 1972 or 1976 Winter Olympics.
 In 1987, the International Olympic Committee (IOC) decided to allow professional athletes to compete in the Olympics, and starting in 1998, the NHL allowed its players to participate.
 Women's ice hockey was added in 1992 and the first tournament was held at the 1998 Winter Olympics.
 Both events have been held at every Olympic Games since.
