The first record of the Olympic Games dates from 776 BC but it is likely that many competitions were held before then. The modern Olympic Games began in 1896. America hosted the modern Olympics 4 times, Australia twice, and in 1980 it was Moscow that hosted the Summer Olympic Games.
No Olympics were held in 1916, 1940 and 1944 because of war. The Winter Olympics began in 1924, originally the same year as the summer competition, but now are held on alternate years. The Olympic Games have сhanged over time and regulated by the International Olympic Committees. Almost every sport, from archery to yachting, is included in the Games and it continues to be the world's largest sports event.
