Title: Curling at the Winter Olympics
Content:  Curling was included in the program of the inaugural Winter Olympic Games in 1924 in Chamonix although the results of that competition were not considered official by the International Olympic Committee until 2006. Curling was a demonstration sport at the 1932 Games, and then again after a lengthy absence in 1988 and 1992. The sport was finally added to the official program for the 1998 Nagano Games. Until 2018, men's and women's events were contested. An additional event, mixed doubles, was rejected for 2010 because the Olympic Programme Commission felt it had not developed enough, but was approved for the 2018 Winter Olympics at an IOC Executive Board meeting in June 2015. Since the 1998 Olympics, Canada has generally dominated the sport with their men's teams winning gold in 2006, 2010, and 2014, and silver in 1998 and 2002. The women's team won gold in 1998 and 2014, a silver in 2010, and a bronze in 2002 and 2006. Their mixed doubles team won gold in 2018. The related ice stock sport (Eisstockschießen in German) was a demonstration event in 1936 and 1964. These events are not considered additional demonstrations of curling.
Title: Curling
Content:   Curling has been a medal sport in the Winter Olympic Games since the 1998 Winter Olympics. It currently includes men's, women's and mixed doubles tournaments (the mixed doubles event was held for the first time in 2018). In February 2002, the International Olympic Committee retroactively decided that the curling competition from the 1924 Winter Olympics (originally called Semaine des Sports d'Hiver, or International Winter Sports Week) would be considered official Olympic events and no longer be considered demonstration events. Thus, the first Olympic medals in curling, which at the time was played outdoors, were awarded for the 1924 Winter Games, with the gold medal 
Title: Curling at the 1924 Winter Olympics
Content:  The curling event at the 1924 Winter Olympics was contested only by men. It was the first curling event in Olympic history. In February 2006, a few days before the start of the 2006 Winter Olympics, the International Olympic Committee ruled that the curling medals were part of the official Olympic programme in 1924, and not a demonstration event as many authoritative sources had previously claimed (although the IOC itself had never done so). This official confirmation was the culmination of an investigative campaign begun by the Glasgow-based newspaper The Herald, on behalf of the families of the eight British contestants who won the first curling gold medals. The winning team had been selected by the Royal Caledonian Curling Club, Perth.

Title: List of Olympic medalists in curling
Content:  Curling 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 (IOC). The tournament was won by a team from the Royal Caledonian Curling Club in Scotland, who represented Great Britain. In 2006, Scottish newspaper The 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
