In the 1970s, the American city of Denver, chosen to host the 1976 Winter Olympics, rejected the bid after a statewide referendum. About ten cities applied to take over the Games and Innsbruck was selected. The main reasons for this choice were the venues built for the 1964 Games, which kept costs down, and their good organization during the 1964 Olympics. The Olympic venues subsequently hosted various sports competitions such as the Four Hills Tournament, Bobsleigh and Luge World Cup events, the Winter Universiade and the Ice Hockey World Championship in 2005 and the first Winter Youth Olympic Games in 2012.
