Pac-Man is an arcade game created by Toru Iwatani and released by Namco in May 22, 1980 under the name "Puck Man". The name of the game was later changed to "Pac-Man" due to vandalism of the "P" in "Puck" into an offensive word. The game wasn't intended to be too popular at first, but when released, the game was a huge success. This resulted in many sequels of the game, including Ms. Pac-Man. The game has been cloned innumerable times, and re-released in many compilations.
