For the last three years, the folks over at ESPN have put together a list of the biggest names in the world of sport, which they've dubbed the "World Fame 100." The ranking, according to ESPN, is created by "a proprietary formula that took into account three fame factors: Google Trend score, social media following and endorsement dollars." One could argue that taking just three variables into account isn't a broad enough examination of "fame" (the number of golfers who made the list is the best indication of that), but at this moment, it's the best we've got.
