Arena Indoor Football
About Arena Indoor Football
This version of American (or Gridiron) Football has become extremely popular in Mexico.
Indoor Football, also known as Arena Football was developed in 1986 as an 8v8 form of Indoor American Football. After an initial few seasons where the game was developed with a 4 team league, a full seasons League with eventually over a dozen teams was developed in the 1990 which was considered by the Wall Street Journal to be a fifth major.
The Arena Football League over-expanded in the 2000s with a Minor League, and its importance (and number of teams) waned since it first experienced financial diffulties in 2009, and it ceased operations after the 2019 season due to the legacy debt incurred.
There is now, however, Indoor Football Leagues all over America, all of which would now be considered Minor League or Semi-Pro (AAA, AA, or even A)
Indoor Football is played on a 50-yard field with two 8-yard endzones, and teams have 5 downs (attempts) to reach the endzone or the ball is turned over. 3 of those downs must be passing plays, making Indoor Football highly explosive and high scoring.
The main difference between Arena Football & Indoor Football is the rebound nets either side of the goalposts in Arena Football, which is the only part of the original patent given to the Arena Football League in 1989, that a subsequent ruling in 1998 ruled was copyright, the rest being Football already in other leagues.
Note: For Women’s Indoor Football Leagues, including both Serious Leagues such as the Super 8 Football League in Baja California (Mexico) and Lingerie/Legends Football Leagues (where the Women wear sexy apparel) see Women’s American Football
Note 2: The American grading system for Pro Leagues is 1. Major League, 2. AAA League, 3. AA League, 4. A League, 5. Semi-Pro State Leagues.
Equivalent to 1. Premier League / Major League Soccer, 2. EFL/USL Championship, 3. EFL/USL League 1, 4. EFL/USL League 2, and 5. National League/NPSL in the English and American Soccer System.
Note 3: League in Bold sometimes considered Major Football Leagues.

American 7s
The idea for American 7s came to Ryan DePaul late in 2002. His High School Football playing career was over and there was no possibility of playing College Football. He was playing pick-up, no pads or helmet football in parks and thought it needed codifying, so in 2005 he began to develop 7v7 No Pads, No Helmet, Tackle American Football.
In 2014 he was approached by lifelong friend and entrepreneur, Sener Korkusuz about launching the League to Major League level. Soon afterwards the American 7s Football League was born, starting its first season in March 2015. [Ref: 1]
