Olympic Games
The Olympic Games programme consists of 35 sports, 30 disciplines and 408 events. For example, wrestling is a Summer Olympic sport, comprising two disciplines: Greco-Roman and Freestyle. It is further broken down into fourteen events for men and four events for women, each representing a different weight class. The Summer Olympics programme includes 26 sports, while the Winter Olympics programme features 15 sports. Athletics, swimming, fencing, and artistic gymnastics are the only summer sports that have never been absent from the Olympic programme. Cross-country skiing, figure skating, ice hockey, Nordic combined, ski jumping, and speed skating have been featured at every Winter Olympics programme since its inception in 1924. Current Olympic sports, like badminton, basketball, and volleyball, first appeared on the programme as demonstration sports, and were later promoted to full Olympic sports. Some sports that were featured in earlier Games were later dropped from the programme.
Rugby sevens at the Summer Olympics
Rugby sevens was one of five sports — golf, karate, roller sports, rugby, and squash — that submitted a proposal to the IOC at the 117th IOC Session meeting in Singapore in 2005 for inclusion in the 2012 games. The IOC stated that no sport would be added unless others were dropped. However, the selection of two sports out of the five nominees as potential 2012 sports went to squash and karate, as determined by a voting procedure.
