The World Professional Darts Championship is 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) now organise their own World Championship in January. As a result, there is no longer a unified World Champion in the game, though the World Darts Federation organizes an official World Championship biennially.
The BDO have organised their version dating back to 1978, when it was held at the Heart of the Midlands nightclub, Nottingham. The following year it moved to the Jollees Cabaret Club, Stoke, where it stayed until 1985. Since then it has been held at the Lakeside Leisure Complex at Frimley Green, Surrey.
The PDC version started in 1994 after "the split", with a field of players containing all active previous World Champions from the BDO. It was originally staged at Purfleet's Circus Tavern, Essex before moving to Alexandra Palace for the 2008 World Championship.
