The British Darts Organisation (BDO) is a governing body for the sport of darts in the United Kingdom. Founded in 1973, it was established to promote and organize darts competitions, ensuring fair play and standard rules. The BDO played a significant role in popularizing darts, especially through its annual championship events. The BDO was known for hosting the World Professional Darts Championship, which became a prestigious tournament in the sport. However, in recent years, the organization faced challenges, leading to a decline in its prominence compared to the Professional Darts Corporation (PDC), which has since taken the lead in professional darts events.
