At the IOC meeting in July 11, 2005, baseball and softball were voted out of the 2012 Summer Olympics in London, Great Britain, becoming the first sport voted out of the Olympics since Polo was eliminated from the 1936 Olympics. The event was last played in the 2008 Olympics in Beijing with South Korea taking the gold. The elimination will excise 16 teams and more than 300 athletes from the 2012 Olympics. The two slots left available by the IOC's elimination were not filled by new sports, so both baseball and softball can reemerge as events in the 2016 Olympics, provided no new sports are added to the games and both receive enough votes to be included. This decision was reaffirmed on February 9, 2006.
Speculation over reasons for removal of baseball and softball from the Olympic games include, but may not be limited to:
After a twenty-year hiatus, Olympic baseball (labeled an exhibition sport/event by the IOC) returned but with tournament formatting (1984 Los Angeles). In 1988 Seoul, it was termed a demonstration sport. Japan defeated the United States in the inaugural tournament finale in 1984. However, in 1988, the United States won over Japan.
Baseball became an official sport at the 1992 Summer Olympics, with the familiar eight team tournament. Players were required to be amateurs. The tournament consisted of a round-robin, in which teams played each of the other teams, followed by semifinals and finals. The format of the competition has remained the same since then, with the only major change being that starting in 2000 players were not required to be amateurs.

The final three places are given to the top three nations at an eight-team tournament held after the continental tournaments. Qualification for this tournament is determined by those continental tournaments. The third and fourth place American teams, second and third place European teams, second and third place Asian teams, first place African team, and first place Oceania team compete in that tournament. 
This qualification tournament is new for 2008. It was created after heavy criticism of the previous qualification standard. In previous Olympics, only two teams from the Americas were able to qualify for the Olympics, despite the fact that the vast majority of the top baseball-playing nations in the world come from this region. Europe, whose baseball nations are substantially weaker, also entered two teams.
The tournament consists of a round-robin preliminary round in which each team plays all 7 of the other teams. Only the top four teams advance to the medals round. In that round, semifinals are played between the 1st/4th place teams and the 2nd/3rd place teams. The semifinal losers then play a bronze medal game, with the winner earning the medal and the loser receiving 4th place. The semifinal winners play in the final, which awards the winner a gold medal and the loser a silver medal.
