In November 2003, Woods became engaged to Elin Nordegren, a Swedish former model and daughter of former minister of migration Barbro Holmberg and radio journalist Thomas Nordegren. They were introduced during The Open Championship in 2001 by Swedish golfer Jesper Parnevik, who had employed her as an au pair. They married on October 5, 2004, at the Sandy Lane resort in Barbados, and lived at Isleworth, a community in Windermere, a suburb of Orlando, Florida. In 2006, they purchased a $39-million estate in Jupiter Island, Florida, and began constructing a 10,000-square-foot home; Woods moved there in 2010 following the couple's divorce.
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.
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, designed to be worn while playing the game, incorporates numerous innovative design features to accommodate golf play. 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.
