Backyar wrestling is a loose term used to describe the controversial practice of professional wrestling as performed by untrained fans in an unsanctioned, non-professional environment. Backyard wrestling is a title applied to home filmed and produced professional wrestling shows, videos, or events carried out by untrained athletes, mostly comprised of males between the ages of 12 and 30. In the years since its formation, Backyard wrestling has developed into an underground scene, where federations often produce, trade and distribute their videos via Internet, and other wrestling publications. Though backyard wrestling was not unheard of prior to the 1990s, the modern backyard wrestling "craze" lasted from roughly 1996 to 2001, during a time when televised professional wrestling was enjoying a period of unparalleled popularity.
