Arena football is a variety of gridiron football designed to be played indoors. The game is played on a smaller field than American or Canadian football, designed to fit in the same surface area as a standard North American ice hockey rink, and features between six and eight players for each team playing at any given time depending on the league, resulting in a faster and higher-scoring game that can be played on the floors of indoor arenas. 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.
