The Arena Football League (AFL) is an indoor American football league founded in 1987 by Jim Foster. It is played indoors on a smaller field than American football, resulting in a faster-paced and higher-scoring game. The sport was invented in the early 1980s and patented by Foster, a former executive of the United States Football League and the National Football League.
On February 17, 2010, the AF1 announced it changed its name to the "Arena Football League", returning to the original league name. The league has its headquarters in Tulsa, Oklahoma and will play its games from April through August. The league's championship game is known as the ArenaBowl.
