OXO – The Birth of Computer Gaming

In 1952, a significant milestone in the history of computing and gaming occurred with the creation of OXO by Alexander S. Douglas. Developed as part of his doctoral dissertation at the University of Cambridge, OXO, also known as Noughts and Crosses, is widely regarded as one of the earliest known computer games.

OXO was a computerised version of tic-tac-toe, designed to run on the EDSAC (Electronic Delay Storage Automatic Calculator), one of the first stored-program computers. This groundbreaking program allowed a human player to compete against the machine, marking a significant step forward in human-computer interaction.

What set OXO apart was its use of a cathode ray tube display to show the game board, making it one of the first games with a graphical display. This visual element was crucial in demonstrating the potential for computers to process and display information in real-time, responding to human input.

Although OXO was primarily an academic exercise and remained largely unknown outside university circles for years, its creation marked a pivotal moment in the history of computing and entertainment technology. It demonstrated that computers could be used for more than just complex calculations and data processing.

The game’s simple yet engaging gameplay laid the groundwork for future developments in computer gaming. It showed that computers could provide interactive entertainment, a concept that would evolve dramatically in the decades to come.

While OXO was far from the complex, graphically rich games we know today, its importance in the history of gaming cannot be overstated. It was a proof of concept that helped pave the way for the entire video game industry.

Douglas’s innovative work with OXO helped to spark interest in the potential of computers for entertainment and interactive experiences. It stands as a testament to the foresight and creativity of early computer scientists, who saw beyond the immediate applications of computing technology to envision a future where computers would play a central role in entertainment and daily life.

The creation of OXO in 1952 thus represents not just the birth of a game, but the dawn of an entirely new form of entertainment that would go on to become a global phenomenon.
