The first video game is generally considered to be Tennis for Two, created by William Higinbotham in 1958. It was a simple tennis game played on an oscilloscope using two paddles and a ball. The game was only played at a Brookhaven National Laboratory open house, and there are no known copies of the game still in existence.
However, there are other early video games that predate Tennis for Two. In 1950, a computer scientist named John McCarthy created a game called “The Hexapawn Game” for the Manchester Mark I computer. This game was also quite simple, but it was the first video game to be played on a digital computer.
Another early video game was “OXO“, created by Alexander S. Douglas in 1952. This game was a simple tic-tac-toe game that was played on a cathode-ray tube display.
These early video games were all very simple and limited in scope, but they laid the foundation for the video games that we enjoy today.
