is a team sport that is contested at the Winter Olympic Games. A men's tournament was held at the 1924 Winter Olympics before the sport was removed from the official programme until the 1998 Games. For 82 years, the 1924 tournament was considered a demonstration sport, so the medals were not officially counted by the International Olympic Committee. The tournament was won by a team from the Royal Caledonian Curling Club in Scotland, who represented Great Britain. In 2006, Scottish newspaperThe Herald conducted an investigation that found evidence that curling had been part of the official programme. The IOC subsequently recognized the top three teams as full medal winners. Although not part of the official programme, curling was contested as a demonstration sport in 1932, 1988 and 1992. Curling was re-added as a demonstration event in 1988 because the Olympics were being held in Calgary, Alberta, Canada, where the sport has a strong following. In November 1992, the NaganoWinter OlympicOrganizing Committee and IOC Coordination Committee reached an agreement to include curling in the official programme of the 1998 Games in Nagano, Japan. Both the men's and women's tournaments have been held at every Winter Olympics since. In total, 132 athletes have won a medal in curling, and 11 have won two. In 2010, Anette Norberg, Eva Lund, Cathrine Lindahl and Anna Le Moine of Sweden won the gold medal in the women's tournament, becoming the first curlers to win consecutive gold medals. Kaitlyn Lawes, John Morris, and Kevin Martin of Canada, Torger Nergård of Norway, John Shuster and Joe Polo of the United States, and Mirjam Ott of Switzerland have also won two medals. Norberg also won a silver in 1988 when curling was a demonstration sport. According to the IOC, Carl August Kronlund of Sweden was the oldest Winter Olympics medallist, winning silver in 1924 at the age of 59. Robin Welsh of Great Britain was the oldest Winter Olympics gold medallist, winning in 1924 when he was 54. Teams from Canada have been successful in the sport since its return to the programme, winning two medals at each Olympics for a total of five gold, three silver and two bronze. Switzerland is the only other nation to win at least one medal at every Olympics since 1998 with one gold, two silver and one bronze. Teams from Norway, Sweden, Great Britain, and the United States have also won gold medals in the sport. A total of 27 medals have been awarded since 1924 and have been won by teams from ten National Olympic Committees.
