"Although Foreman never confirmed exactly how much he has earned from the endorsement, Salton paid him $138 million in 1999 for the right to use his name. Prior to that, he was paid about 40% of the profits on each grill sold (earning him $4.5 million a month in payouts at its peak), yielding an estimated total of over $200 million just from the endorsement through 2011, substantially more than he earned as a boxer."

Not sure if luck or stars just aligned. But that is some legit naming rights. Kudos to maybe, and I mean it... one of the best at it.
