World Rugby organises the Rugby World Cup, which has been held every four years since 1987, the sport's most recognised and most profitable competition.[2] Despite the profitability of the Rugby World Cup, the majority of its revenues and viewers come from a small number of countries. For the 2007 Rugby World Cup final, 87% of viewers came from the Five Nations (England, France, Wales, Ireland, Scotland), 15% came from the Tri-Nations (South Africa, Australia, and New Zealand), with just 2% of viewers coming from all other countries.[3]
