The PBA World Championship is one of five major PBA (Professional Bowlers Association) bowling events. It is one of three PBA Tour major events that are open only to PBA members.

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.

The World Chess Championship 1993 was one of the most controversial matches in chess history, with incumbent World Chess Champion Garry Kasparov, and official challenger Nigel Short, splitting from FIDE, the official world governing body of chess, and playing their title match under the auspices of the Professional Chess Association. In response, FIDE stripped Kasparov of his title, and instead held a title match between Anatoly Karpov and Jan Timman.
