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.
The BDO version dated back to 1978, when it was held at the Heart of the Midlands nightclub, Nottingham.
The PDC version has been running since 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 its current home Alexandra Palace, London, for the 2008 World Championship.
The following sortable table lists all winners of both versions of the World Championship (correct as of 4 January 2025).
