The Professional Darts Corporation (PDC) is a professional darts organisation in the United Kingdom, established in 1992 when a group of leading players split from the British Darts Organisation to form what was initially called the World Darts Council (WDC). Sports promoter Barry Hearn is the PDC chairman. The PDC developed and holds several championship competitions, including the annual PDC World Darts Championship, the UK Open, World Grand Prix, Premier League and World Matchplay. It also runs its own world rankings based on players' performances.
