It's been decades now since we had first video-games with us.In 1950 the first video game was publicly demonstrated called Bertie the Brain(an arcade game of tic-tac-toe).
In 1958 with Tennis for Two,the program simulated a game of tennis. In 1962 the game Spacewar(the first true video game) was released on the PDP-1(Programmed Data Processor-1).The game was copied to several of the early minicomputer installations making it potentially the first video game to be available outside.
In 1972 Pong(a tennis game) was released.The same year in which The Magnavox Odyssey,the first commercial home video game console was released.
