Apple CEO Tim Cook has topped a "Power List" of influential Americans by Out Magazine, a lifestyle publication aimed at the gay and lesbian demographic segment. This is the third year Cook has received the honor, but has never acknowledged his sexual orientation publicly -- leaving the magazine to make a presumption based on his unmarried status and other indicators. While not a factor in running Apple, Cook has been known to be unusually circumspect about his private life -- apart from his devotion to Auburn football.
