Arena Football League The Arena Football League (AFL) is a professional indoor American football league in the United States. It was founded in 1987 by Jim Foster, making it the third longest-running professional football league in North America, after the Canadian Football League (CFL) and the National Football League (NFL). The AFL plays a proprietary code known as arena football, a form of indoor American football played on a 66-by-28 yard field (about a quarter of the surface area of an NFL field), with rules encouraging offensive performance, 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 (USFL) and the NFL.
