The tournament changed sponsorship in 2006, with Bridgestone taking over from NEC as title sponsor. As a part of the original five-year sponsorship agreement, the event continues to be held at its traditional site of the Firestone Country Club in Akron, Ohio; the sponsorship has now been extended to 2014.
Up until 1998, there was a tournament called the World Series of Golf, which was also played at Firestone Country Club for many years, and sponsored by NEC. It was founded as a four man invitational event in 1962, but later became a PGA Tour event, and eventually one of the leading events on the Tour. For many years a victory in the World Series of Golf gave a golfer a 10-year exemption on the Tour, which was 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-Bridgestone Invitational listed above, but produced much the same sort of global field.
