The tournament's most recent edition, in Russia in 2013, was planned to be the last. In October 2009, the International Olympic Committee voted to add men's and women's rugby sevens to the Summer Olympics starting in 2016. World Rugby (then known as the International Rugby Board, or IRB), which runs rugby union around the world, said in September 2009 that it would no longer hold a World Cup if the sport would be part of the Olympics. However, the IRB changed its mind, saying in 2013 that the World Cup would be kept. The next World Cup will be held in 2018, and from that point will continue every four years.
