The World Series of Golf quickly became a leading event on the tour. For many years a victory in it gave a 10-year exemption on the PGA Tour, the same as was granted for a victory in a major championship at that time, and twice as long as is given even for winning a major now. The field consisted of the winners of all the high status men's professional golf tournaments around the world in the previous twelve months. This was quite different from the criteria for the WGC Invitational listed above, but produced much the same sort of global field.
