The BWF World Championships (formerly known as IBF World Championships, also known as the World Badminton Championships) is a tournament organized by the Badminton World Federation (BWF) to crown the best badminton players in the world. The tournament started in 1977 and was held once every three years until 1983. However, the IBF faced difficulty in hosting the first two events as the World Badminton Federation (which later merged with the IBF to form one badminton federation) hosted the same tournament a year after the IBF World Championships with the same goals. Started 1985, the tournament became bi-annual and played once every two years until 2005. Starting 2006, the tournament was changed to an annual event on the BWF calendar with the goal to give more chances for the players to be crowned as official "World Champions". However, the tournament will not be held once every four years to give way to the Olympic Games.
