The Golf Digest 50 lists the 50 professional golfers with the highest total annual income. Total income is the sum of both on-course and off-course earnings. Tiger Woods ranked first with a total annual income of $122 million. However, almost $100 million of this total was from off-course activities such as product endorsements and personal appearances. The 10 professional golfers with the highest off-course income are shown in the following table (Golf Digest website, February 2008).
