The World Professional Darts Championship was one of the most important tournaments in the darts calendar. Originally held as an annual event between 1978 and 1993, players then broke off into two separate organisations after a controversial split in the game. Each organisation, the British Darts Organisation (BDO) and the Professional Darts Corporation (PDC) since organised their own World Championship, the former in January the latter in December. As a result, there no longer was an unified world champion in the sport for nearly three decades. This ended when the BDO ceased to exist in 2020, leaving the PDC as the sole organisation crowning a world professional darts champion.
