The list of Olympic sports has changed considerably during the course of Olympic history, and has gradually increased over time. The only summer sports that have never been absent from the Olympic program are athletics, aquatics (the discipline of swimming has been in every Olympics), cycling, fencing, and gymnastics (the discipline of artistic gymnastics has been in every Olympics).
The Winter Olympic Games (French: Jeux olympiques d'hiver) is a major international multi-sport event held once every four years for sports practiced on snow and ice. The first Winter Olympic Games, the 1924 Winter Olympics, were held in Chamonix, France.
At the 1921 Olympic Congress, in Lausanne, it was decided to hold a winter version of the Olympic Games. A winter sports week (actually 11 days) was held in 1924 in Chamonix , France.  The IOC ruled that the Winter Olympic Games be celebrated every four years on the same year as the summer games.
