The 1950's to 1970's

The video gaming culture gradually originated from early cathode ray tube based missile defence systems in the late 1940’s which later became simple games during the 1950’s. The computers were usually mainframe computers which later converted to various platforms due to the ever growing technology.
“In 1952, A.S. Douglas wrote his PhD degree at the University of Cambridge on Human-Computer interaction. Douglas created the first graphical computer game - a version of Tic-Tac-Toe.”
I think this was the first ever real attempt in making a graphical game and although it seems basic and probably doesn’t have the same complexity as a modern video game it had human input so it was to be considered some as sort of a game. Six years later William Higinbotham created the first ever proper video game and this is a considerable step forward as it tried to mimic a real life sport which was tennis.

In 1961 a group of students at MIT programmed a game called Space war. The game consisted of two human players capable of firing missiles while a large star in the centre of the screen created a hazard for the spaceships. Space war is often credited as the most influential game.
In 1966 Ralph Baer and Bill Harisson created a simple video game named Chase and this game was the first time a video game was played on a standard television set. They soon created Light Gunand developed several video games with Bill Rusch in 1967 and within a year a prototype was completed featuring several games such as table tennis and target shooting. In 1969 they were showing off their first home video game console to manufactures. The same year AT&T programmer Jeremy Ben wrote a video game called Space Travel for the Multics operating system. The main objective of this game was to successfully land a space craft, this game was later ported to a different system but it proved to be very costly so Ben looked for a less expensive computer to use, he then ported the game to PDP-7 with the help of Dennis Ritchie and by developing a software for this machine the development process of the Unix operating system began and Space Travel has been called the first ever UNIX application.
The Magnovox was believed to be the first video game console with rudimentary graphics in 1972 and it was the first video game console that can be played at home. This console had a basic version of Pong which was probable the most important achievement which was released by Atari in November 1972 in arcades. The name was given because of two reasons, the first reason was that “pong” was the sound the game makes when the ball hits the paddle or side of the screen and the second reason was that “ping-pong” was already copyrighted.
The home video games became popular and were copied and sold by numerous companies, but they could not survive due to strong competition from Atari, Magnavox and others.
