Professional Indoor Football League (1998)

The Professional Indoor Football League (PIFL) was the second league to successfully play indoor football as a paid pro-league sport, after the Arena Football League (AFL). Since the AFL had a patent given in 1990 on the gameplay of "Arena Football" (mainly the endzone nets), the PIFL played with mostly the same rules, but without the endzone nets. The PIFL only lasted one season (1998) under that name.
