Synchronized diving was adopted as an Olympic sport in 2000.
Two divers form a team and perform dives simultaneously.
The dives are identical.
It used to be possible to dive opposites, also known as a pinwheel, but this is no longer part of competitive synchronized diving.
For example, one diver would perform a forward dive and the other an inward dive in the same position, or one would do a reverse and the other a back movement.
In these events, the diving would be judged both on the quality of execution and the synchronicity – in timing of take-off and entry, height and forward travel.
The first Olympic demonstration was at the 1952 Olympic Games, where the Helsinki officials welcomed Kay Curtis and lit a torch in her honor.
Curtis died in 1980, but synchronized swimming did not become an official Olympic sport until the 1984 Summer Olympic Games.
It was not until 1968 that synchronized swimming became officially recognized by FINA as the fourth water sport next to swimming, platform diving and water polo.
From 1984 through 1992, the Summer Olympic Games featured solo and duet competitions, but they both were dropped in 1996 in favor of team competition.
At the 2000 Olympic Games, however, the duet competition was restored and is now featured alongside the team competition.  
Diving was first introduced in the official programme of the Summer Olympic Games at the 1904 Games of St. Louis and has been an Olympic sport since.
It was known as "fancy diving" for the acrobatic stunts performed by divers during the dive (such as somersaults and twists).
This discipline of Aquatics, along with swimming, synchronized swimming and water polo, is regulated and supervised by the International Swimming Federation (FINA), the international federation (IF) for aquatic sports. 
Zhang Mengmeng (; born July 8, 1980), is a sport anchor and commentator at China Central Television.
Prior to joining CCTV-5, Zhang won the "Who will Comment the Beijing Olympics" sport host competition.
Zhang Mengmeng specializes in synchronized swimming and diving.
She received a junior sport broadcasting award in 2010.
Zhang, a Jinan Shandong girl, articulates.
Her reaction is very fast; however, she was not Cobain by birth, before she was a synchronized swimmer.
Zhang Mengmeng was two-time national youth team of synchronized swimming at the various achieved outstanding results in a level in the national competition.
In addition to the synchronized swimming at the top national levels, Zhang Mengmeng was also an aerobics as well as rhythmic gymnastics national levels athletes.
In addition, she was swimming, aerobics, rhythmic gymnastics and track and field at the national level referee, as well as tennis, volleyball, basketball and table tennis national referees.
Beijing time on August 11 afternoon, during the broadcasting of the semi-finals of the 2012 London Olympic Games men 10m platform diving competition by CCTV-13, Zhang Mengmeng hosted with guests Hu Jia (diver).
For some time, perhaps due to Zhang Mengmeng forgot to turn off the microphone, her comments on British and Australian athletes clearly presented out, which caused an internet uproar. 
The first Olympic diving events were contested by men and consisted of a platform diving event ("fancy high diving") and also a plunge for distance event, which heralded victorious the diver who could reach the farthest underwater, while remaining motionless after a ground-level standing dive.
At the 1908 Summer Olympics, men's springboard diving was added to the programme replacing the plunge for distance, regarded as uninteresting.
Women's diving debut happened at the 1912 Summer Olympics in the platform event and was expanded to springboard diving at the 1920 Summer Olympics.
A parallel platform diving event for men, called "plain high diving", was presented at the Games of the V Olympiad.
No acrobatic moves were allowed, only a simple straight dive off the platform.
It was last contested at the 1924 Summer Olympics after which it was merged with "fancy high diving" into one competition renamed "highboard diving" (or just "high diving").
By the time of the 1996 Summer Olympics, the diving events were exactly the same as in 1928.
However, four years later in Sydney, the inclusion of a synchronized diving variant for the springboard and platform events elevated the list up to eight events.
Another important change to the sport occurred in the 1984 Summer Olympics, when China was first allowed to compete, ending the ban imposed upon them by FINA because of their nation's government.
China has won many medals since then.
