ROLLERBLADING, or in-line skating, dates from 1979, when Scott and Brennan Olson, two brothers from Minnesota, discovered an antique in-line skate in a sporting goods store. Inspired by the design, the brothers forged
a primitive rollerblade by attaching polyurethane wheels and a rubber toe-brake to a pair of ice-hockey boots. Four years later, Scott Olson founded Rollerblade, Inc., from which the sport of in-line skating takes its common name. Two decades later, competitive rollerblading attracted thousands of participants and viewers every year, while millions of Americans of all ages turned to rollerblading as a form of recreation and low-impact exercise.
