An exhibition game (also known as a friendly, a scrimmage, a demonstration, a preseason game, a warmup match, or a preparation match, depending at least in part on the sport) is a sporting event whose prize money and impact on the player's or the team's rankings is either zero or otherwise greatly reduced. In team sports, matches of this type are often used to help coaches and managers select and condition players for the competitive matches of a league season or tournament. If the players usually play in different teams in other leagues, exhibition games offer an opportunity for the players to learn to work with each other. The games can be held between separate teams or between parts of the same team. An exhibition game may also be used to settle a challenge, to provide professional entertainment, to promote the sport, to commemorate an anniversary or a famous player, or to raise money for charities. Several sports leagues hold all-star games to showcase their best players against each other, while other exhibitions games may pit participants from two different leagues or countries to unofficially determine who would be the best in the world. International competitions like the Olympic Games may also hold exhibition games as part of a demonstration sport. An exhibition game can also serve as a 'warm up match' for upcoming league or official matches. Association football In the early days of association football, friendlies were the most common type of match. However, with the development of The Football League in England in 1888, league and cup tournaments became the primary methods of competition. The significance of friendly matches thus declined since the 19th century: by 2000, national leagues were established in almost every country throughout the world, with local or regional leagues for lower-level teams. Club football Since the introduction of league football, most club sides play a number of friendlies before the start of each season (called pre-season friendlies). Friendly football matches are considered to be non-competitive and are only used to "warm up" players for a new season/competitive match. Some rules may be changed or experimented with (such as unlimited substitutions, which allow teams to play less experienced players). Frequently such games take place between a large club and nearby smaller clubs, such as those between Newcastle United and Gateshead. Although most friendlies are simply one-off matches arranged between the clubs in which a
