In October and November 2004, the IOC established an Olympic Programme Commission, which was tasked with reviewing the sports on the Olympic programme and all non-Olympic recognised sports. The goal was to apply a systematic approach to establishing the Olympic programme for each celebration of the Games. The commission formulated seven criteria to judge whether a sport should be included on the Olympic programme. These criteria are history and tradition of the sport, universality, popularity of the sport, image, athletes' health, development of the International Federation that governs the sport, and costs of holding the sport. From this study five recognised sports emerged as candidates for inclusion at the 2012 Summer Olympics: golf, karate, rugby sevens, roller sports and squash. These sports were reviewed by the IOC Executive Board and then referred to the General Session in Singapore in July 2005. Of the five sports recommended for inclusion only two were selected as finalists: karate and squash. Neither sport attained the required two-thirds vote and consequently they were not promoted to the Olympic programme. In October 2009 the IOC voted to instate golf and rugby sevens as Olympic sports for the 2016 and 2020 Summer Olympic Games.
