The George Foreman story is incredible. One of boxing's all time greats, in the first half of his career, George Foreman knocked out the previously undefeated 'Smokin' Joe Frazier, and tangled with Muhammad Ali in the 'Rumble in the Jungle', which may be the most famous fight of all time. He retired in the late 1980s, but bad financial planning left him almost bankrupt, so he returned to the ring and amazingly became a world champion again in 1994, at 45 years of age.
Citing healthy eating as the reason for his longevity, he was approached by a company making a new kind of grill, seeking his endorsement. The George Foreman grill was born, and with his licensing of his name to the product earning him 40% of the value of each grill sold, Foreman was quickly making $4.5m every month as the grill became a worldwide must-have kitchen accessory.
