Ms. Pac-Man was originally created by 2 programmers at General Computer Corporation who altered a Pac-Man board. The original name for the new game was Crazy Otto. General Computer Corporation sold the rights to Crazy Otto to Midway who changed the name to Ms. Pac-Man and distributed the game without Namco's consent. To avoid loss of other licenses and lawsuits, Midway turned over rights to Ms. Pac-Man to Namco in 1982.
The ghosts are named Inky, Pinky, Blinky, and Sue.
