International Olympic Committee
The IOC organises the modern Olympic Games and Youth Olympic Games, held in summer and winter, every four years. The first Summer Olympics organised by the IOC was held in Athens, Greece, in 1896; the first Winter Olympics was in Chamonix, France, in 1924. Until 1992, both Summer and Winter Olympics were held in the same year. After that year, however, the IOC shifted the Winter Olympics to the even years between Summer Games, to help space the planning of the two events from one another, and improve the financial balance of the IOC, which receives greater income on Olympic years. The first Summer Youth Olympics were in Singapore in 2010 and the first Winter Youth Olympics were held in Innsbruck in 2012.
List of outdoor ice hockey games
In the early history of hockey, games were played outdoors on rivers, lakes, and other naturally occurring ice surfaces. In fact, the first indoor game, held in 1875, was a novelty at the time, yet after that the game moved inside. While the first Olympic hockey tournament, held in 1920, was played indoors, games at the first Winter Olympics in 1924 were the first of several such tournaments to be played outdoors. Games at the World Championships were occasionally played outdoors, including the 1957 gold medal game between the Soviet Union and Sweden at the Lenin Stadium in Moscow. The attendance at that game was approximately 55,000, a number that stood as a record for more than 40 years. In 1954, the Detroit Red Wings of the National Hockey League (NHL) played an exhibition game on an outdoor ice surface against the inmates of Michigan's Marquette Branch Prison.
