Hundreds of sports exist worldwide. In North America, ice hockey, American football and baseball are very popular, while in China, people primarily enjoy badminton, table tennis and basketball. Cricket is the second-most-watched sport in the world and is particularly popular in India, Pakistan and Australia. Soccer, or Association Football, is by far the most popular sport worldwide, as people throughout Europe, Africa, South America and the Middle East enjoy it.
A sport is any activity that requires skill, involves an element of competition between at least two people or teams and has a set of rules to govern it. Most sports rely on some physical ability and exertion. However, sports can also be mind-focused, such as chess; motorized, such as boating or Formula 1; coordinated, such as billiards; and animal-supported, such as equestrian sports. A modern and increasingly popular form of sport is electronic, such as video gaming.
Humans participated in organized sports as early as 2,000 B.C, based on Chinese artifacts. Records show that the first Olympic games occurred in 776 B.C. Since industrialization, people have more leisure time, and as a result, they increased their participation in sports. As of 2013, the worldwide sports industry is worth approximately $620 billion.
