Indianapolis Colts quarterback Peyton Manning was listed as number one on the second annual Bloomberg BusinessWeek/Horrow Sports Ventures Power 100 list ahead of such sports luminaries as snowboarder and Olympic medal winner Shaun White, Miami Heat star LeBron James, and golfer Tiger Woods.

The list rankings were determined by examining on-field play over the last two years weighing it with off-field factors such endorsement income and fan popularity. Two examples of this were skier Lindsey Vonn who, off the heels of a starmaking performance at last winter's Olympics, jumped to #13 on the list after not being ranked the year prior and James who felled from #2 to #11 due to his backlash and criticism of his controversial decision to join the Miami Heat.

The NFL had the most players on the list with 27, Major League Baseball was second with 23, the NBA notched 18 spots. 7 golfers, 7 NASCAR drivers, 6 tennis players, 5 Olympians, 3 NHL players, 2 soccer players, a cyclist (Lance Armstrong), and a boxer (Manny Pacquiao) rounded out the list.
