The Soviet Union won its third gold medal with a 7–1 record in the 1968 Grenoble Olympics. Czechoslovakia and Canada won the silver and bronze medals. It was the last time that the Olympics were counted as the World Championships. In 1970, Canada withdrew from international ice hockey competition protesting the use of full-time "amateurs" by the Soviet Union and Czechoslovakia, and the team did not participate in the 1972 and 1976 Winter Olympics. Led by goaltender Vladislav Tretiak and forwards Valeri Kharlamov, Alexander Yakushev, Vladimir Petrov and Boris Mikhailov, the Soviet team won gold at both the 1972 Games in Sapporo, Japan and 1976 Winter Olympics in Innsbruck, Austria. In 1971, the United States finished last at the World Championships and was relegated to Pool B. The team qualified for the 1972 Olympics and won silver, making it the first Pool B team to win an Olympic medal. Czechoslovakia won the bronze medal in 1972. In 1976, Czechoslovakia won the silver and West Germany won bronze. Along with Canada, the Swedish team did not participate in the 1976 tournament joining the boycott.
