The Winter Olympic Games is a major international sporting event which occurs once every four years. The first celebration of the Winter Olympics was held in Chamonix, France, in 1924. The original sports were alpine and cross-country skiing, figure skating, ice hockey,Nordic combined, ski jumping and speed skating. The Games were held every four years from 1924 until 1936, after which they were interrupted by World War II. The Olympics resumed in 1948 and were celebrated every four years. The Winter and Summer Olympic Games were held in the same years until 1992, after a 1986 decision by the International Olympic Committee (IOC) to place the Summer and Winter Games on separate four-year cycles in alternating even-numbered years.
