How many times has tennis been in the Olympics?

As a subject matter expert in the history of sports, particularly tennis, I can provide you with a detailed answer to your question. Tennis has been a part of the Olympic Games on several occasions, with its history in the Olympics being somewhat intermittent. Tennis was first introduced at the Olympics in the year 1896, but it was not until the 1900 Games that women were allowed to compete in singles and mixed doubles tennis events. However, after the 1924 Olympics, tennis was removed from the official Olympic program. It was then played as a demonstration sport in the 1968 and 1984 Olympics before being reinstated as a full medal sport at the 1988 Seoul Olympics. To answer your question directly, tennis has been a part of the Olympics as a full medal sport in the following years: 1896, 1900, 1988, 1992, 1996, 2000, 2004, 2008, 2012, and 2016. This makes a total of 10 times as a full medal sport. If we include the demonstration years, the count would be higher, but since demonstration sports do not award official Olympic medals, they are often not counted in the total.

Women were allowed to start to compete in singles and mixed doubles tennis events at the Olympic Games in 1900. Between 1928 and 1988, tennis was not included in the official Olympic program. Demonstration tennis events were, however, held twice, first in 1968 and later 1984. It was reinstated as a medal sport in 1988.
