Fantasy football (association)
Fantasy football (less commonly referred to as fantasy association football worldwide but known as fantasy soccer in the United States) is a game in which participants assemble an imaginary team of real life footballers and score points based on those players' actual statistical performance or their perceived contribution on the field of play. Usually players are selected from one specific division in a particular country, although there are many variations. The original game was created in England by Bernie Donnelly on Saturday 14 August 1971 and is still going strong 45 years later. Fantasy football has evolved in recent years from a simple recreational activity into a significant business due to exposure via the internet.
Arena football
Arena football is a variety of indoor gridiron football played by the Arena Football League (AFL) and China Arena Football League (CAFL). The game is played indoors on a smaller field than American or Canadian outdoor football, resulting in a faster and higher-scoring game. The sport was invented in 1981, and patented in 1987, by Jim Foster, a former executive of the National Football League and the United States Football League. The name is trademarked by Gridiron Enterprises and had a proprietary format until its patent expired in 2007. Due to the patent, other indoor American football leagues that launched following the popularity of the original AFL developed variants on the arena rules.
