Polo is played professionally in many countries, notably Argentina, Australia, Brazil, Canada, Chile, Dominican Republic, France, Germany, Iran, India, New Zealand, Mexico, Pakistan, Jamaica, Spain, South Africa, Switzerland, the United Kingdom, and the United States, and is now an active sport in 77 countries. Although its tenure as an Olympic sport was limited to 1900–1939, in 1998 the International Olympic Committee recognised it as a sport with a bona fide international governing body, the Federation of International Polo. The World Polo Championship is held every three years by the Federation.
