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."
At the end of each year, the top 125 in FedEx Cup points (top 125 on the money list before 2013) receive a tour card for the following season, which gives them exemption from qualifying for most of the next year's tournaments. However, at some events, known as invitationals, exemptions apply only to the previous year's top 70 players. Since 2013, players who are ranked between 126–200 in FedEx Cup points (and are not already exempt by other means) are eligible for entry in the Korn Ferry Tour Finals, where they can regain their PGA Tour privileges. Non-exempt players who finish 126th-150th in the FedEx Cup but fail to regain their PGA Tour cards are given conditional PGA Tour status for the season and are fully exempt on the Korn Ferry Tour.
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.
