How many Olympic games have taken place in the US?
United States
The market for professional sports in the United States is roughly $69 billion, roughly 50% larger than that of all of Europe, the Middle East, and Africa combined. Baseball has been regarded as the national sport since the late 19th century, while American football is now by several measures the most popular spectator sport. Basketball and ice hockey are the country's next two leading professional team sports. These four major sports, when played professionally, each occupy a season at different, but overlapping, times of the year. College football and basketball attract large audiences. Boxing and horse racing were once the most watched individual sports, but they have been eclipsed by golf and auto racing, particularly NASCAR. In the 21st century, televised mixed martial arts has also gained a strong following of regular viewers. While soccer is less popular in the United States than in many other nations, the men's national soccer team has been to the past six World Cups and the women are #1 in the women's world rankings. While most major U.S. sports have evolved out of European practices, basketball, volleyball, skateboarding, snowboarding, and cheerleading are American inventions, some of which have become popular in other countries. Lacrosse and surfing arose from Native American and Native Hawaiian activities that predate Western contact. Eight Olympic Games have taken place in the United States. The United States has won 2,400 medals at the Summer Olympic Games, more than any other country, and 281 in the Winter Olympic Games, the second most by 2014.
