Computer Space, and Pong
The very first commercially released coin-operated video game was Computer Space. The famous white Prototype for Computer Space is in the collection of the Museum of the Game -- the older sister of MOOT. Computer Space and its futuristic fiberglass case was intriguing, and modestly successful, and launched a new industry. It directly led lead to the creation of Atari and its first release, the coin-operated version of Pong.
