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.
1928 Winter Olympics
The 1928 Games were the first true "Winter Olympics" held on its own as they were not in conjunction with a "Summer Olympics". The preceding 1924 Games were retroactively renamed the inaugural Winter Olympics, though they had been in fact part of the 1924 Summer Olympics. All preceding Winter Events of the Olympic Games were the winter sports part of the schedule of the Summer Games, and not held as a separate Winter Games. These games also replaced the now redundant Nordic Games, that were held quadrennially since early in the century.
