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.
1948 Winter Olympics
There were 28 nations that marched in the opening ceremonies on January 30, 1948. Nearly 670 athletes competed in 22 events in four sports. The Games also featured two demonstration sports: military patrol, which later became the biathlon, and winter pentathlon, which was discontinued after these Games. Notable performances were turned in by figure skaters Dick Button and Barbara Ann Scott and skier Henri Oreiller. Most of the athletic venues were already in existence from the first time St. Moritz hosted the Winter Games in 1928. All of the venues were outdoors, which meant the Games were heavily dependent on favorable weather conditions.
