Power 100 Methodology
Working with Horrow Sports Ventures and CSE, an integrated sports and marketing firm in Atlanta, Bloomberg BusinessWeek.com developed the methodology for the 2010 edition of the Power 100 ranking of the most powerful athletes in professional sports. The Power 100 rankings are based on a blended mix of athletes' "on-field" and "off-field" performance to determine which athletes are having the greatest overall impact in the world of sports. On-field scoring is determined by statistically ranking each athlete's sports performance within his or her peer group over a two-year period. For each sport, key performance metrics include such measures as points scored, money earned, laps lead, and batting average, to name a few. This ranking is then adjusted by the overall popularity of the sport itself, based on an index of fan avidity and TV viewership. The off-field scoring is developed from hundreds of surveys on athletes and how the general public perceives them. The data was compiled by E-Poll Market Research, a leading provider of custom research services and products for entertainment and media companies, using their E-Score® Celebrity database. Athlete rankings are based on such attributes as awareness, appeal, trustworthiness, and influence. In addition, the amount of endorsement dollars each athlete earns rounds out the off-field ranking.
