It was written by Alexander S. (Sandy) Douglas as an illustration for his [[Doctor of Philosophy|Ph.D.]] thesis on human-computer interaction for the [[University of Cambridge]]. ''OXO'' was the first known (graphical) game to run on a computer. However, there is a patent dating from 1947–1948 that describes a missile simulation game utilizing a [[cathode ray tube]].<ref>Thomas T. Goldsmith Jr. and Estle Ray Mann filed a United States patent application on January 25, 1947 and [http://www.jmargolin.com/patents/2455992.pdf U.S. Patent #2 455 992] issued on December 14, 1948.</ref> The player played against the computer, and output was displayed on the computer's 35×16 [[pixel]] [[cathode ray tube]]. The [[source code]] was short, yet it played a perfect game of noughts and crosses. ''OXO'' did not have widespread popularity because the EDSAC was a computer unique to [[Cambridge]]. ''OXO'' consisted of a digital display system that showed a "pod" visual system like scoreboards at the Olympics. It is argued that ''OXO'' was the [[first video game]] ever made, predating even William Higinbotham's ''[[Tennis For Two]]'' from 1958. ==Startscreen== <pre> 9 8 7 NOUGHTS AND CROSSES 6 5 4 BY 3 2 1 A S DOUGLAS, C.1952 LOADING PLEASE WAIT...
