Baseball - a past sport at the Olympics
Baseball has had a long history of competition in various forms at the Olympic Games. Early on it was included as a demonstration sport only, with it not getting full sport status until 1992, and being dropped again after 2008.
Baseball was played as a demonstration sport at many Olympic Games from 1908 until 1988. See Baseball as an Olympic demonstration sport.
Baseball became an "official" sport at the 1992 Olympics, with the familiar eight team tournament. Cuba won the first gold medal ever awarded.
Until the 2000 Olympics in Sydney, participation in the baseball tournament at the Olympic Games was restricted to amateurs. In the Games since 2000, professional players were permitted to play.
Baseball (along with softball) was dropped from the 2012 Games and has not appeared at the Games since.
