| | American football in TutorGig Encyclopedia |
 | | Canadian football, which also descended from rugby, is closely related to the American sport with a few key differences; the word "football" in Canada can mean American football or Canadian football depending on context. |
 | | Tackle football is often banned in American schoolyards in favor of touch football, which uses two-hand touching instead of tackling; or flag football in which a player is "tackled" when an opponent pulls a flag off a belt attached to the player's waist. |
 | | There is a widespread perception that football teams based in schools and public recreational leagues consume far more than their fair share of the sports budget, although sales of tickets to college (and to some extent high school) football games often make it a revenue-producing sport. |
