The 2010 Winter Olympics, officially known as the XXI Olympic Winter Games and also known as Vancouver 2010, were an international winter multi-sport event held from February 12 to 28, 2010 in Vancouver, British Columbia, Canada, with some events held in the surrounding suburbs of Richmond, West Vancouver and the University of British Columbia, and in the nearby resort town of Whistler. It was regarded by the Olympic Committee to be among the most successful Olympic games in history, in both attendance and coverage. Approximately 2,600 athletes from 82 nations participated in 86 events in fifteen disciplines. Both the Winter Olympic and Paralympic Games were organized by the Vancouver Organizing Committee (VANOC), headed by John Furlong. The 2010 Winter Games were the third Olympics to be hosted by Canada, and the first to be held within the province of British Columbia. Canada had hosted the 1976 Summer Olympics in Montreal, Quebec, and the 1988 Winter Olympics in Calgary, Alberta.
