Tiger Woods, one of the greatest golfers the game has ever seen and arguably one of the greatest athletes of all time, has joined an exclusive list of sports billionaires.

Good to Know: Forbes estimates that Woods' net worth has surpassed the $1 billion mark, making him one of only three athletes to ever reach billionaire status.

The estimate is based on Woods' lifetime earnings, but despite winning 82 times on the PGA Tour, including 15 major championships,

the vast majority of Woods' wealth comes from endorsement deals. Other notable endorsements include Rolex and Gatorade,

Woods also signed equipment sponsorships with TaylorMade and Bridgestone Golf following a nearly two-year absence,

The iconic golfer has also increased his net worth by investing in several golf-related startups. But it's never been about the money for Woods,

who has grown tremendously through his golf career with near-impossible putts and worn his emotions on his sleeve,

Woods' magic touch around the greens was often complemented by fiery celebrations followed by roars that could be heard across the course.
