Extreme sport

Extreme sports (also called action sports and adventurous sports) is a popular term for certain activities perceived as having a high level of inherent danger. These activities often involve speed, height, a high level of physical exertion, and highly specialized gear. The definition of an extreme sport is not exact and the origin of the term is unclear, but it gained popularity in the 1990s when it was picked up by marketing companies to promote the X Games and when the Extreme Sports Channel and Extreme.com launched.
