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
As well as rugby sevens, baseball and softball, which were dropped from the Olympic programme in 2005, karate, squash, golf and roller sports (inline speed skating) were all seeking to be included in the 2016 games and leaders of the seven sports made formal presentations to the IOC executive board in June 2009. A new system was in place at this session in which a sport now needs only a simple majority rather than the two-thirds majority that was required before.
