First held in Providence, Rhode Island, in October 1993, Extreme Games were promoted by the sports cable company ESPN to highlight rising sports (many of them noted for their danger) that networks had previously neglected. Featuring such sports as street luge, skateboarding, skiboarding, bungy jumping, downhill in-line skating, skysurfing, wakeboarding and bicycle stunts, they emphasize daredevil acts rather than races against time. Planned as biannual events, the first games were so successful (watched by over 220 million domestic viewers and carried in over 150 countries) that organizers decided to hold the games every year. The US Post Office offered a 1999 stamp series honoring them.
