Noughts and Crosses. A Platinum Jubilee Fact.

In 1952 one of the first computer games was programmed and run on a computer the size of your house!

Alexander Douglas was studying at Cambridge University for a PhD, when he wrote a simulation of Noughts and Crosses (known in other places as ‘Tic-Tac-Toe’), as part of his thesis on human-computer interaction. The game was called OXO, and ran on the university’s EDSAC computer and the display was a repurposed oscilloscope with a 35×16 dot matrix cathode ray tube. The player could choose whether they would start or the computer and the input device was a rotary telephone dial.
