The Arena Football League (AFL) played a form of indoor American football played on a 66-by-28 yard field. The sport was invented in the early 1980s and patented by Jim Foster, a former executive of the United States Football League and the NFL. The AFL played its first official games in the 1987 season, running for 22 consecutive seasons until going bankrupt following the 2008 season. A third AFL, which is not directly connected to the previous two iterations of the league but claiming their histories, intends to launch in 2024.
