International competition

The annual men's Ice Hockey World Championships are highly regarded by Europeans, but they are less important to North Americans because they coincide with the Stanley Cup playoffs. Consequently, Canada, the United States, and other countries with large numbers of NHL players have not always been able to field their best possible teams because many of their top players are playing for the Stanley Cup. Furthermore, for many years professionals were barred from play. Now that many Europeans play in the NHL, the world championships no longer represent all of the world's top players.
Hockey has been played at the Winter Olympics since 1924 (and at the summer games in 1920). Canada won six of the first seven gold medals. The United States won their first gold medal in 1960. The USSR won all but two Olympic ice hockey gold medals from 1956 to 1988 and won a final time as the Unified Team at the 1992 Albertville Olympics. U.S. amateur college players defeated the heavily favored Soviet squad on the way to winning the gold medal at the 1980 Lake Placid Olympics.
The 1972 Summit Series and 1974 Summit Series, established Canada and the USSR as a major international ice hockey rivalry. It was followed by five Canada Cup tournaments, where the best players from every hockey nation could play, and two exhibition series, the 1979 Challenge Cup and Rendez-vous '87 where the best players from the NHL played the USSR. The Canada Cup tournament later became the World Cup of Hockey, played in 1996 and 2004. The United States won in 1996 and Canada won in 2004. Since 1998, NHL professionals have played in the Olympics, giving the best players in the world more opportunities to face off.
There have been nine women's world championships, beginning in 1990. Women's hockey has been played at the Olympics since 1998. The 2006 Winter Olympic final between Canada and Sweden marked the first women's world championship or Olympic final that did not involve both Canada and the United States
