There are also a number of events which are recognized by the PGA Tour, but which do not count towards the official money list. Most of these take place in the off season (November and December). This slate of unofficial, often made-for-TV events (which have included the PGA Grand Slam of Golf, the Wendy's 3-Tour Challenge, the Franklin Templeton Shootout, the Skins Game, etc.) is referred to as the "Challenge Season" or more commonly as the "Silly Season."
The PGA Tour (stylized in all capital letters as PGA TOUR by its officials) is the organizer of the main professional golf tours played primarily by men in the United States and North America. It organizes most of the events on the flagship annual series of tournaments also known as the PGA Tour, as well as PGA Tour Champions (for golfers age 50 and older) and the Korn Ferry Tour (for professional players who have not yet qualified to play in the PGA Tour), as well as PGA Tour Canada, PGA Tour Latinoamérica, and PGA Tour China. The PGA Tour is a nonprofit organization headquartered in Ponte Vedra Beach, Florida, a suburb of Jacksonville.
The tour began 91 years ago in 1929 and at various times the tournament players had attempted to operate independently from the club professionals. With an increase of revenue in the late 1960s due to expanded television coverage, a dispute arose between the touring professionals and the PGA of America on how to distribute the windfall. The tour players wanted larger purses, where the PGA desired the money to go to the general fund to help grow the game at the local level. Following the final major in July 1968 at the PGA Championship, several leading tour pros voiced their dissatisfaction with the venue and the abundance of club pros in the field. The increased friction resulted in a new entity in August, what would eventually become the PGA Tour. Tournament players formed their own organization, American Professional Golfers, Inc. (APG), independent of the PGA of America. Its headquarters were in New York City.
