The game is called Puck Man in Japan. The game was named "Pac-Man" in the United States so that nobody could change the "P" to "F". There were many sequels and remakes based on the game. Hanna-Barbera made a animated TV show airing on ABC in the early 1970s. The game was also part of "Namco Museum" games. There is a "Namco Museum Remix" for the Wii.
