The 2010 Winter Olympics, officially known as the XXI Olympic Winter Games, was a winter multi-sport event held in Vancouver, British Columbia, Canada, from February 12 to February 28. A total of 2,632 athletes representing 82 National Olympic Committees (NOCs) (+2 from 2006 Olympics) participated in 86 events (+2 from 2006) from 15 different sports and disciplines (unchanged from 2006).
Athletes from 26 NOCs won at least one medal, and athletes from 19 of these NOCs secured at least one gold. For the first time, Canada won a gold medal at an Olympic Games it hosted, having failed to do so at both the 1976 Summer Olympics in Montreal and the 1988 Winter Olympics in Calgary. In contrast to the lack of gold medals at these previous Olympics, the Canadian team finished first overall in gold medal wins, and became the first host nation—since Norway in 1952—to lead the gold medal count, with 14 medals. In doing so, it also broke the record for the most golds won by a NOC at a single Winter Olympics (the previous was 13, set by the Soviet Union in 1976 and matched by Norway in 2002). The United States placed first in total medals—its second time doing so in a Winter Games—and set a new record for most medals won by a NOC at a single Winter Olympics, with 37 (the previous record was 36, established by Germany in 2002). Athletes from Slovakia and Belarus won the first Winter Olympic gold medals for their nations.
