In 2010, the 1st Youth Olympic Games sanctioned by the IOC were held in Singapore. Taekwondo was an official event with five weight categories in both male and female divisions. Two years later, it was taekwondo's big moment.
For the 2012 London Olympics, the WTF had made dramatic changes. Protector and Scoring Systems and Instant Video Replays were both implemented. Some 6,000 people watched the bouts in the sold-out ExCel arena, as a differentiated points scoring system made bouts unpredictable and a reduced mat size made matches more exciting. In addition, the WTF Demonstration Team performed four times every day.
Finally, London Olympic taekwondo distributed eight gold medals to eight countries, laying to rest concerns that it was a Korea-dominated sport.
