While there are varying views on what should be considered the dawn of computer games, it is reasonable to believe that the very

simple game designed by Thomas T. Goldsmith and Estle Ray Mann, for playing on a Cathode Ray Tube (CRT) in 1947 marked the dawn of computer games. Conventionally, however,
A.S Douglas who developed OXO, a graphical version of noughts and crosses (
Tic-Tac-Toe), in 1952 at the University of Cambridge, is considered the
father of computer games. Douglas developed this game to demonstrate his thesis on Human-Computer-Interaction, and it was played on the EDSAC computer. Despite its technological antiquity, Tic-Tac Toe is still popular in some age groups!!!
William Higginbotham, who, in 1958 created a game called 'Tennis for Two' on an oscilloscope is another individual credited

with the
invention of video games. This game was created primarily to entertain visitors at Brookhaven National Laboratory in New York. This game shows a simplified tennis court from the side, where the player tries to play the ball over the net, against
gravity pull. The game had two controllers, with a knob for controlling the trajectory, and a button for firing the ball over the net. Pong (discussed below), an innovation of Tennis for Two that found immense popularity in arcade and home consloe versions, was the first video game played by many people.
In 1961, a group of students at MIT, including Steve Russell, programmed a game called Spacewar! on the

then-new DEC PDP-1. The game pitted two human players against each other, each controlling a space ship capable of firing missiles. A
black hole in the center created a large gravitational field and another source of hazard. This game was soon distributed with new DEC computers and traded throughout primitive cyberspace. Presented at the MIT Science Open House in 1962, it was the first widely available and influential game.
Following this, in 1966, Ralph Baer (then at Sanders Associates) created a simple video game called Chase that could be displayed on a standard television set. Baer continued development, and in 1968 he had a prototype that could play several different games, including versions of table tennis and target shooting. Under Baer, Bill Harrison developed the light gun and, with Bill Rusch, developed video games.
