The Nintendo
The introduction of the Nintendo games console in 1983 ushered in the modern computer game era, and with it obesity, teen violence and the poor form of former Liverpool F.C. goalkeeper David James.
The way was paved for the Nintendo after the Video Game Crashes of 1977 and 1983, the first caused by the burn-out of popular Atari game "Pong," which involved watching a small square moving agonizingly slowly from one side of the TV screen to the other, and the second by poor sales of Pacman.
