A study comparing eight tournaments Woods played in 2007 with the same tournaments he missed in 2008 found ratings down 47% overall, according to the Nielsen Co. During his professional career, TV ratings of Masters tournaments that Woods has won have drawn 20% more viewers than those he hasn't.
Double-digit declines were recorded in several tournaments during Woods' off year, but the sharpest decline was posted in the PGA Championship in 2007 and 2008. On the final day in 2007, when Woods won by two strokes, more than 9 million viewers were watching. The next year, when Padraig Harrington won and Woods didn't play, viewership dropped 57.6%.
