Modern pentathlon again as one of the 25 core sports of the Olympic program through to 2020. The governing body, Union Internationale de Pentathlon Moderne (UIPM), administers the international sport in more than 90 countries in all the continents of the world. The foundation of the modern pentathlon is disputed. On the one hand, Baron Pierre de Coubertin, the founder of the modern Olympic Games, claimed authorship.

Olympic Games session following a celebration of the Olympic Games. During such revisions, sports can be excluded or included in the programme on the basis of a two-thirds majority vote of the members of the IOC. There are recognised sports that have never been on an Olympic programme in any capacity, including chess and surfing. In October and November 2004, the IOC established an Olympic Programme Commission, which was tasked with reviewing the sports on the Olympic programme and all non-Olympic recognised sports. The goal was to apply a systematic approach to establishing the Olympic programme for each celebration of the Games.
