Badminton World Invitational Championships

World Invitation Championships was the invitational event in badminton, which was conducted in the absence of a world championship (the first badminton world championship took place only in 1977) brought together top players from all major badminton nations in a kind of unofficial world championship. The winner of this tournament is not called as the World Champions, since the players who compete are only those who receive invitations from the event organizer.
