History of Computer Games 1950-70

So, Computer games, wonderful creations. I've always been interested since the age of 8. I have always thought that the first computer games were created during the gameboy era, oh how wrong I was. In fact, the very first computer game was created in 1952, by A.S. Douglas, who created the first digital version of tic-tac-toe.
Tennis for Two was created for entertainment purposes by William Higinbotham. The game was displayed on an oscilloscope, featuring a basic, 2D tennis court. At the time it was fun to play and became rather addictive.

Although this was the first of its kind, it is rarely credited as the first computer game. Spacewar! was made in 1961 by Steve Russel, which became the first influencial and widely available game of its time. Even now, we still play arcade games based on the design of Spacewar!, they're just nicer to look at.

Although Spacewar is comonly known as the first widely available game, it wasn't displayed on a TV screen. In fact, it was shown on the DEC PDP-1, a new computer at the time. Ralph Baer was the first person to produce a game that was displayed on a TV screen, called Chase.
