The World Memory Championships is an organized competition of memory sports in which competitors memorize as much information as possible within a given period of time. The championship has taken place annually since 1991, with the exception of 1992. It was originated by Tony Buzan and co founded by Tony Buzan and Ray Keene. It continues to be organized by the World Memory Sports Council (WMSC), which was jointly founded by Tony Buzan and Ray Keene. In 2016, due to a dispute between some players and the WMSC, the International Association of Memory (IAM) was launched. From 2017 onward, both organizations have hosted their own world championships.
The current WMSC world champion is Emma Alam of Pakistan. The current IAM world champion is Andrea Muzii of Italy.
