American Indoor Football is a professional indoor football league that has gone through various incarnations since 2005.The AIFL began as a regional league with six franchises on the East Coast of the United States in 2005; after a rapid and largely failed expansion effort in 2006 most of the league’s remaining teams jumped to the new AIFA (the rest joined the short-lived WIFL). The AIFA expanded throughout existing territory and in 2008 expanded into the Western United States.
