context_page_description: Olympic sports are contested in the Summer Olympic Games and Winter Olympic Games. The 2016 Summer Olympics included 28 sports, with five additional sports due to be added to the 2020 Summer Olympics program; the 2014 Winter Olympics included seven sports. The number and types of events may change slightly from one Olympiad to another. Each Olympic sport is represented by an international governing body, namely an International Federation. The International Olympic Committee establishes a hierarchy of sports, disciplines, and events. According to this hierarchy, each Olympic sport can be subdivided into multiple disciplines, which are often mistaken as distinct sports. Examples include swimming and water polo, which are in fact disciplines of the sport of aquatics, and figure skating and speed skating, which are both disciplines of the sport of ice skating. In turn, disciplines are subdivided into events, for which Olympic medals are awarded. A sport or discipline is included in the Olympic program if the IOC determines it to be widely practiced around the world, that is, the popularity of a given sport or discipline is indicated by the number of countries that compete in it.
context_section_description: The list of Olympic sports has changed considerably during the course of Olympic history, and has gradually increased until the early 2000s, when the IOC decided to cap the number of sports in the Summer Olympics at 28.
  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 only winter sports that were included in all Winter Olympic Games are skiing (only nordic skiing), skating (figure skating and speed skating), and ice hockey. Figure skating and ice hockey were also included in the Summer Olympics before the Winter Olympics were introduced in 1924.
  For most of the 20th century, demonstration sports were included in many Olympic Games, usually to promote a non-Olympic sport popular in the host country, or to gauge interest and support for the sport.
  The competitions and ceremonies in these sports were identical to official Olympic sports, except that the medals were not counted in the official record.
  Some demonstration sports, like baseball and curling, were later added to the official Olympic program.
  This changed when the International Olympic Committee decided in 1989 to eliminate demonstration sports from Olympics Games after 1992. An exception was made in 2008, when the Beijing Organizing Committee received permission to organize a wushu tournament.
  A sport or discipline may be included in the Olympic program if the IOC determines that it is widely practiced around the world, that is, the number of countries and continents that regularly compete in a given sport is the indicator of the sport's prevalence. The requirements for winter sports are considerably lower than for summer sports since many fewer nations compete in winter sports. The IOC also has lower requirements for inclusion of sports and disciplines for women for the same reason. 
  Women are still barred from several disciplines; but on the other hand, there are women-only disciplines, such as rhythmic gymnastics and synchronized swimming.
  Sports that depend primarily on mechanical propulsion, such as motor sports, may not be considered for recognition as Olympic sports, though there were power-boating events in the early days of the Olympics before this rule was enacted by the IOC.  Part of the story of the founding of aviation sports' international governing body, the FAI, originated from an IOC meeting in Brussels, Belgium on June 10, 1905.
  These criteria are only a threshold for consideration as Olympic sport. In order to be admitted to the Olympic program, the IOC Session has to approve its inclusion. There are many sports that easily make the required numbers but are not recognized as Olympic sports, mainly because the IOC has decided to put a limit on the number of sports, as well as events and athletes, in the Summer Olympics in order not to increase them from the 28 sports, 300 events, and 10,000 athletes of the 2000 Summer Olympics.
  No such limits exist in the Winter Olympics and the number of events and athletes continue to increase, but no sport has been added since 1998. The latest winter sport added to the Winter Olympics was curling in 1998.
  Previous Olympic Games included sports which are no longer present on the current program, like polo and tug of war. In the early days of the modern Olympics, the organizers were able to decide which sports or disciplines were included on the program, until the IOC took control of the program in 1924. As a result, a number of sports were on the Olympic program for relatively brief periods before 1924. These sports, known as discontinued sports, were removed because of lack of interest or absence of an appropriate governing body, or because they became fully professional at the time that the Olympic Games were strictly for amateurs, as in the case of tennis.
  Several discontinued sports, such as archery and tennis, were later readmitted to the Olympic program (in 1972 and 1984, respectively). Curling,
