13. Henry Chon, CEO, Cyworld
In South Korea, an estimated 25 percent of the population (and 90 percent of people in their teens and twenties) have Cyworld accounts, where individuals design miniature animated avatars to represent them in its unique online space. In 2006 CEO Henry Chon brought Cyworld to U.S. shores. Though Cyworld hasn't yet achieved comparable success here, MySpace shouldn't rest easy if Chon's track record is any indication of future competition.
