Endorsements

During the first decade of his professional career, Woods was the world's most marketable athlete. Shortly after his 21st birthday in 1996, he signed endorsement deals with numerous companies, including General Motors, Titleist, General Mills, American Express, Accenture, and Nike. In 2000, he signed a 5-year, $105 million contract extension with Nike, which was the largest endorsement package signed by a professional athlete at that time. Woods's endorsement has been credited with playing a significant role in taking the Nike Golf brand from a "start-up" golf company earlier in the previous decade to becoming the leading golf apparel company in the world and a major player in the equipment and golf ball market. Nike Golf is one of the fastest growing brands in the sport, with an estimated $600 million in sales. Woods has been described as the "ultimate endorser" for Nike Golf, frequently seen wearing Nike gear during tournaments, and even in advertisements for other products. Woods receives a percentage from the sales of Nike Golf apparel, footwear, golf equipment, golf balls, and has a building named after him at Nike's headquarters campus in Beaverton, Oregon.

In 2002, Woods was involved in every aspect of the launch of Buick 's Rendezvous SUV. A company spokesman stated that Buick was happy with the value of Woods's endorsement, pointing out that more than 130,000 Rendezvous vehicles were sold in 2002 and 2003. "That exceeded our forecasts," he was quoted as saying, "It has to be in recognition of Tiger." In February 2004, Buick renewed Woods's endorsement contract for another five years, in a deal reportedly worth $40 million.

Woods collaborated closely with TAG Heuer to develop the world's first professional golf watch, which was released in April 2005. The lightweight, titanium -construction watch, incorporates features to facilitate wearing the watch while playing the game. It is capable of absorbing up to 5,000 Gs of shock, far in excess of the forces generated by a normal golf swing. In 2006, the TAG Heuer Professional Golf Watch won the prestigious iF product design award in the Leisure/Lifestyle category.

Woods also endorsed the Tiger Woods PGA Tour series of video games; he has done so since 1999. In 2006, he signed a six-year contract with Electronic Arts, the series' publisher.

In February 2007, Woods, Roger Federer, and Thierry Henry became ambassadors for the " Gillette Champions" marketing campaign. Gillette did not disclose financial terms, though an expert estimated the deal could total between $10 million and $20 million.

In October 2007, Gatorade announced that Woods would have his own brand of sports drink starting in March 2008. "Gatorade Tiger" was his first U.S. deal with a beverage company and his first licensing agreement. Although no figures were officially disclosed, Golfweek magazine reported that it was for five years and could pay him as much as $100 million. The company decided in early fall 2009 to discontinue the drink due to weak sales.

In October 2012, it was announced that Woods signed an exclusive endorsement deal with Fuse Science, Inc, a sports nutrition firm.

In 1997, Woods and fellow golfer Arnold Palmer initiated a civil case against Bruce Matthews (the owner of Gotta Have It Golf, Inc.) and others in the effort to stop the unauthorized sale of their images and alleged signatures in the memorabilia market. Matthews and associated parties counterclaimed that Woods and his company, ETW Corporation, committed several acts including breach of contract, breach of implied duty of good faith, and violations of Florida's Deceptive and Unfair Trade Practices Act. Palmer also was named in the counter-suit, accused of violating the same licensing agreement in conjunction with his company Arnold Palmer Enterprises.

On March 12, 2014, a Florida jury found in favor of Gotta Have It on its breach of contract and other related claims, rejected ETW's counterclaims, and awarded Gotta Have It $668,346 in damages. The award may end up exceeding $1 million once interest has been factored in, though the ruling may be appealed.

In August 2016, Woods announced that he would be seeking a new golf equipment partner after the news of Nike's exit from the equipment industry. It was announced on January 25, 2017, that he would be signing a new club deal with TaylorMade. He added the 2016 M2 driver along with the 2017 M1 fairway woods, with irons to be custom made at a later date. He also added his Scotty Cameron Newport 2 GSS, a club he used to win 13 of his 15 majors. Also, in late 2016, he would add Monster Energy as his primary bag sponsor, replacing MusclePharm.

On January 8, 2024, Woods announced that he would be parting ways with Nike after 27 years, ending one of the most lucrative endorsements any athlete has had.
