In most cases, sports involve competition. The results of a sport are judged subjectively by the participants, but it is possible to grade the performance objectively by using handicaps and penalties. In other sports, the time taken to complete a course is the objective measurement. Gymnastics, boxing, mixed martial arts, and golf are examples of sports where the result is determined by the judges, but the activities are not regulated. The result of a game is generally declared a win if one team does not lose.
The World Health Organization (WHO) estimates the value of the global sporting industry at $620 billion in 2013. The sport industry has evolved over the last century. There are several forms of sport, including recreational, competitive, and spectator sports. The value of each sport varies greatly, from individual games to large teams. The sports industry continues to grow as a global business, and the UK alone is among the leading nations in the world. However, there are a few important exceptions.
Organized sport includes a variety of disciplines. The history of sport and its evolution is fascinating. Evidence suggests that ancient China practiced gymnastics, which was later incorporated into modern sports. Spectator sports, such as wrestling and football, have been an important source of entertainment for non-participants. The popularity of sport varies widely around the world, and spectator sports tend to draw large crowds to stadiums or broadcast them to a wider audience.
