The tournament is considered to be the most prestigious event in the sport of badminton and is often referred to as the World Championships or the Badminton World Championships.

The BWF World Championships was first held in 1977 in Malmo, Sweden, and has been held every year since then except for 1983 when it was canceled due to a boycott by the International Badminton Federation. The tournament is open to all players who are members of the BWF, and the winners of the tournament are crowned as world champions in their respective categories.

The tournament features five categories of competition: men's singles, women's singles, men's doubles, women's doubles, and mixed doubles. The competition consists of a single-elimination tournament with players or pairs seeded according to their world ranking. The top seeds in each category receive a bye in the first round, while the other players or pairs compete in a preliminary round.
