A spectator sport is a sport that is characterized by the presence of spectators, or watchers, at its matches. For instance, American football, association football, baseball, basketball, professional boxing, cricket, field hockey, Formula One, ice hockey, rugby football, team handball, tennis and volleyball are spectator sports, while hunting or underwater hockey typically are not. Spectator sports may be professional sports or amateur sports. They often are distinguished from participant sports, which are more recreational; golf and tennis can be either. Association football, also known as soccer, is by far the most watched sport on the planet.
The increasing broadcasting of sports events, along with media reporting can affect the number of people attending sports due to the ability to experience the sport without the need to physically attend and sometimes an increasingly enhanced experience including highlights, replays, commentary, statistics and analysis. Some sports are particularly known as "armchair sports" or "lounge room sports" due to the quality of the broadcasting experience in comparison to the live experience.
Spectator sports have built their own set of culture and traditions including, in the United States, cheerleading and pre-game and half time entertainment such as fireworks, particularly for big games such as competition decider events and international tests. The passion of some sports fans also means that there are occasionally spectator incidents.
