Here is the list of Popular discontinued sports in Olympic
A cricket tournament, played as part of the 1900 Summer Olympics, took place on 19–20 August at the Vélodrome de Vincennes. The only match of the tournament was played between teams representing Great Britain and France, and was won by 158 runs by Great Britain. At the time of introduction popularity of cricket was minimal so International Olympic Committee (IOC) dropped the idea of continuing cricket in Olympics. International Cricket Council (ICC) want to reintroduce cricket’s shorter format T20 into Olympics but due to various reasons it's being postponed.
Golf was featured in the Summer Olympic Games official programme in 1900 and 1904. At the IOC session in Copenhagen in October 2009, the IOC decided to reinstate this event for the 2016 Summer Olympics. The event will be open to professional golfers.
- Rugby Union
Rugby union has been a men's medal sport at the modern Summer Olympic Games, being played at four of the first seven competitions. The sport debuted at the 1900 Paris games where the gold medal was won by the host nation. It was subsequently featured at the London games in 1908, the Antwerp games in 1920 and the Paris games in 1924. The United States is the most successful nation in Olympic rugby tournaments, having won the gold medal in both 1920 and 1924. After 1924, rugby union was dropped as an Olympic sport. Rugby will return for the 2016 Games in Rio de Janeiro as Rugby sevens.
Baseball had its unofficial debut at the 1904 Summer Games, and it became an official Olympic sport at the 1992 Summer Olympics. Baseball has a long history as an exhibition/demonstration sport in the Olympics prior to its receiving official medal status by the IOC. The event was last played in the 2008 Olympics in Beijing with South Korea taking the gold.
Polo was introduced in the Summer Olympics at the 1900 Games. It was contested in another four Olympiads before being removed from the official programme after the 1936 Summer Olympics. There has been skepticism about polo’s suitability as a modern Olympic sport, due in part to the low number of countries that would be able to field a national team at the highest level.
