Blood sport

A blood sport or bloodsport is a category of sport or entertainment that involves bloodshed. Common examples of the former include combat sports such as cockfighting and dog fighting and some forms of hunting and fishing. Activities characterized as blood sports, but involving only human participants, include the Ancient Roman gladiatorial games.
Current issues.
Online videos.
Many online video-sharing websites such as YouTube do not allow videos of animal bloodsports to be shown on the site.
Animal fighting.
Limitations on blood sports have been enacted in much of the world. Certain blood sports remain legal under varying degrees of control in certain locations (e.g., bullfighting and cockfighting) but have declined in popularity elsewhere. Proponents of blood sports are widely cited to believe that they are traditional within the culture. Bullfighting aficionados, for example, do not regard bullfighting as a sport but as a cultural activity. It is sometimes called a tragic spectacle, because in many forms of the event, the bull is invariably killed and the bullfighter is always at risk of death.
Hunting and recreational fishing.
Animal rights and animal welfare advocates have extended the term "blood sport" to various types of hunting. Trophy hunting and fox hunting in particular have been disparaged as blood sports by those concerned about animal welfare, animal ethics and conservation.
Recreational fishing has sometimes been described as a blood sport by those within the recreation.
In fiction.
Blood sports have been a common theme in fiction. While historical fiction depicts real-life sports such as gladiatorial games and jousting, speculative fiction, not least dystopic science fiction suggests variants of blood sports in a contemporary or future society. Some popular works themed on blood sports are "Battle Royale", "The Hunger Games", "The Running Man", "The Long Walk", "Fight Club", "Death Race 2000", "Amores Perros", "Bloodsport", "Danganronpa", and "The Most Dangerous Game". Blood sports are also a common setting for video games ("Unreal Tournament", "Street Fighter", etc.), making up much of the fighting game genre.
Developed science fiction universes such as "Star Wars" and "Doctor Who" feature different blood sports.
