The championships will comprise four tournaments featuring the world's leading players, and they will all be held in the US.
"Golf is a global sport now," Woods told the UK's Guardian newspaper. "Look at the world rankings - there are players from all over the world, and that's indicative of how our game has changed. We have a responsibility to play round the world and to grow the game as much as we can."
George O'Grady, chief executive of the European Tour, has promised to fight the PGA's decision, with many top European players set to spend more time playing in the US.
Woods' opinions carry huge weight in golf given the commerical impact his rise to prominence has had on the sport.
