'''''OXO''''' (also known as '''''Noughts and Crosses''''') is a [[tic-tac-toe]] [[computer game]] made for the [[EDSAC]] computer in [[1952]]. 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.
