Extreme sports

Extreme Sports (also called action sport and adventure sport) is a media term for certain activities perceived as having a high level of inherent danger.[1][2][3] These activities often involve speed, height, high level of physical exertion, highly specialized gear or spectacular stunts.[1]
At present date, there are no careful studies or statistics of deaths to separate activities with low or normal level of danger from those with high level of danger. It is instead used as a marketing term in promoting events such as the X Games.

The definition of extreme sports may have shifted over the years due to marketing trends. When the term first surfaced circa the late 1980s/early 1990s, it was used for adult sports such as skydiving, scuba diving, surfing, rock climbing, snow skiing, water skiing, snowboarding, mountain biking, mountaineering, storm chasing, hang gliding, and bungee jumping, many of which were undergoing an unprecedented growth in popularity at the time. Outside magazine, not the X Games, epitomized the meaning of the term, and if there was a clothing style associated with extreme sports it was an "outdoorsy" look favoring brand names associated with mountaineering or backpacking such as The North Face and Patagonia, Teva sandals or hiking boots for footwear, etc. The term nowadays applies more to youth sports like skateboarding, snowboarding, aggressive skating, FMX and BMX and is closely associated with marketing efforts aimed at the younger generation (e.g. the ad campaigns of Mountain Dew), and with their favored styles of clothing and music, especially the kind of urban baggy look associated with skateboarders, and loud, fast alternative rock. This shift in styles may also be partly a generational shift, as Baby Boomers and Generation X have aged and marketing efforts associated with extreme sports shifted toward the younger Generation Y demographic sometime in the mid to late 1990s.
