Since 2006, international competition uses the 3 x 21 rally point system as endorsed by the Badminton World Federation.
The original scoring system in badminton dates back to as early as 1873.
The traditional scoring system also allows for a single game to determine a match or rubber.
Usually, the shuttle is dropped on top of the net; the server is appointed by the direction it points to when it falls to the floor.
[2] In 2002 the International Badminton Federation (BWF), concerned with the unpredictable and often lengthy time required for matches, decided to experiment with a different scoring system to improve the commercial and especially the broadcasting appeal of the sport[citation needed].
This experiment was abandoned and replaced by a modified version of the traditional scoring system.
[5] In the old system, competitors may not be able to score after many exchanges, since serving is often slightly more difficult than defending, especially in professional badminton.
[7] In the BWF Annual Grand Meeting in 2014 a review of the scoring system was performed.
