Olympic sports

Currently, the Olympic program consists of 35 different sports, 53 disciplines and more than 400 events. The Summer Olympics includes 28 sports with 38 disciplines and the Winter Olympics includes 7 sports with 15 disciplines. Nine sports were on the original Olympic programme in 1896: athletics, cycling, fencing, gymnastics, weightlifting, shooting, swimming, tennis, and wrestling. If the 1896 rowing events had not been cancelled due to bad weather, they would have been included in this list as well.

At the most recent Winter Olympics, 15 disciplines in seven sports were featured. Of these, cross country skiing, figure skating, ice hockey, Nordic combined, ski jumping, and speed skating have been featured on the programme at all Winter Olympics. In addition, figure skating made it's debut at the London Summer Olympics of 1908 and ice hockey was first contested at the 1920 Summer Olympics in Antwerp before the introduction of a separate Winter Olympics.

In recent years, the IOC has added several new sports to the programme to attract attention from young spectators. Examples of such sports include snowboarding and beach volleyball. There is currently an effort underway to make Cricket an Olympic sport. It appears though the growth in the number of sports included at an Olympics has . The IOC decided to discontinue baseball and softball beginning in 2012. Rugby was played in the 1900, 1908, 1920 and 1924 Olympics but was discontinued in 1928.

Rule 48.1 of the Olympic Charter requires that there be a minimum of 15 Olympic sports at each Summer Games. Following its 114th Session (Mexico 2002), the IOC also decided to limit the programme of the Summer Games to a maximum of 28 sports, 301 events, and 10,500 athletes. The Olympic sports are defined as those governed by the International Federations listed in Rule 46 of the Olympic Charter. A two-thirds vote of the IOC is required to amend the Charter to promote a Recognised Federation to Olympic status and therefore make the sports it governs eligible for inclusion on the Olympic programme. Rule 47 of the Charter requires that only Olympic sports may be included in the programme.

The IOC reviews the Olympic programme at the first Session following each Olympiad. A simple majority is required for an Olympic sport to be included in the Olympic programme. Under the current rules, an Olympic sport not selected for inclusion in a particular Games remains an Olympic sport and may be included again later with a simple majority. At the 117th IOC Session, 26 sports were included in the programme for London 2012.

Until 1992, the Olympics also often featured demonstration sports. The objective was for these sports to reach a larger audience; the winners of these events are not official Olympic champions. These sports were sometimes sports popular only in the host nation, but internationally known sports have also been demonstrated. Some demonstration sports eventually were included as full-medal events.
