In the days and months following Woods' admission of multiple infidelities, several companies re-evaluated their relationships with him. Accenture, AT&T, Gatorade and General Motors completely ended their sponsorship deals, while Gillette suspended advertising featuring Woods. TAG Heuer dropped Woods from advertising in December 2009 and officially ended their deal when his contract expired in August 2011. Golf Digest suspended Woods's monthly column beginning with the February 2010 issue. In contrast, Nike continued to support Woods, as did Electronic Arts, which was working with Woods on the game Tiger Woods PGA Tour Online. A December 2009 study estimated the shareholder loss caused by Woods's affairs to be between $5 billion and $12 billion.
Buick Open: Shot a final-round 69 and coasted to a three-shot victory with a 20-under 268 at the Buick Open for the 69th PGA TOUR title of his career. Improved to 36-1 when he had the outright lead after 54 holes. The win was his fourth of the season in just 11 starts since returning from knee surgery and the 69th of his career. He also claimed 500 FedExCup points and moved to the top of the standings. Reached victory No. 69 at the age of 33 years and seven months–almost seven years faster than Jack Nicklaus and eight years sooner than Sam Snead. Shot a 71 in the first round and came back with the best five-hole start of his career–beginning 6-under in the second round–en route to a 9-under 63 for his best score in relation to par in four years. Shot a 65 in the third round and held a one-shot lead going into Sunday.
In 2000, Woods won six consecutive events on the PGA Tour, which was the longest winning streak since Ben Hogan did it in 1948. One of these was the U.S. Open, where he broke or tied nine tournament records in what Sports Illustrated called "the greatest performance in golf history", in which Woods won the tournament by a record 15-stroke margin and earned a check for $800,000. At age 24, he became the youngest golfer to achieve the Career Grand Slam. At the end of 2000, Woods had won nine of the twenty PGA Tour events he entered and had broken the record for lowest scoring average in tour history. He was named the Sports Illustrated Sportsman of the Year, the only athlete to be honored twice, and was ranked by Golf Digest magazine as the twelfth-best golfer of all time.
Kultida (née Punsawad) is originally from Thailand, where Earl had met her when he was on a tour of duty there in 1968. She is of mixed Thai, Chinese, and Dutch ancestry. Earl was a retired lieutenant colonel and Vietnam War veteran who reported African American, Chinese, and Native American descent. Earl's mother Maude Carter was light skinned. Tiger describes his ethnic make-up as "Cablinasian" (a syllabic abbreviation he coined from Caucasian, Black, American Indian, and Asian).
Early in Woods' career, a small number of golf industry analysts expressed concern about his impact on the competitiveness of the game and the public appeal of professional golf. Sportswriter Bill Lyon of Knight Ridder asked in a column, "Isn't Tiger Woods actually bad for golf?" (though Lyon ultimately concluded that he was not). At first, some pundits feared that Woods would drive the spirit of competition out of the game of golf by making existing courses obsolete and relegating opponents to simply competing for second place each week.
