The First Video Games
The most resounding impact William āWillyā Higinbotham had on the world had nothing to do with video games. Higinbotham worked on the team that developed the first atomic bomb at Los Alamos Laboratory (now Los Alamos Research Laboratory), and after that experience he became a leading figure in the nuclear non-proliferation movement as a founder and chair of the Federation of American Scientists.2 As a relative footnote to his role in such pivotal global events, Higinbotham is also known for having arguably developed the first electronic video game. While serving as a senior physicist at Brookhaven National Laboratory, Higinbotham was aware that even though the innovations his facility was producing could be world-changing, they were not necessarily impressive on display to visitors (his work in Los Alamos being a notable exception). To entertain attendees at an annual public visitorsā day in 1958, he spent a few hours developing a rudimentary tennis simulation using analog computer technology designed to track missile trajectories and a pair of 5-inch oscilloscope screens.2 The result, Tennis for Two, was a popular feature for visitors, but appeared only once more at the next annual visitorsā day. Higinbotham couldnāt even be bothered to pursue a patent for his patched-together diversion, which was based in technology that was already on its way to obsolescence; digital computers had already begun to appear, and much larger cathode ray tube displays were in use in household televisions. Only more than a decade later, when the eerily similar Pong burst onto the commercial scene, did the significance of Higinbothamās Tennis for Two as a milestone in video game history become apparent.3
As with most remembered milestones in the history of communication technology, the actual story of the first video game is not so clear-cut as Higinbotham and Tennis for Two. Just as tales of Alexander Graham Bellās telephone and Samuel Morseās telegraph are famous, but oversimplified by the absence of references to earlier prototypes and competing developments,4 there were other prototypes that could be called electronic games that were developed before Higinbothamās 1958 demonstration. OXO, a simulation of the popular pencil-and-paper game called āNoughts and Crossesā or āTic Tac Toe,ā was developed in 1952 as part of Alexander āSandyā Douglasā doctoral work at the University of Cambridge.5 While the program ran on a digital computer (the Electronic Delay Storage Automatic Calculator, or EDSAC) and used a cathode ray tube display, OXO often eludes credit as the first video game because it lacked a moving graphic display. A similar effort was a draughts (checkers) simulation made in 1951 by Christopher Strachey at Englandās National Physical Laboratory in London, which was a pioneering artificial intelligence program.6 British engineering firm Ferranti exhibited a computer developed to play the game Nim using a series of lights as an interface at the Festival of Britain in 1951,7 and famed British mathematician Alan Turing worked with Dietrich Prinz on a rudimentary chess simulation that had no visual interface and was programmed by Prinz in 1951.8
Another argument for the earliest origin of the video game can be based on a patent for a āCathode Ray Tube Amusement Deviceā filed in 1947 and issued in 1948.9 That device, developed by Thomas T. Goldsmith, Jr. and Estle Ray Mann at Dumont Laboratories in Upper Montclair, New Jersey, allowed users to control a dot on a screen to aim at paper overlay targets, with successful targeting tracked mechanically rather than by computer processing. While sharing some visual display traits with Higinbothamās Tennis for Two game, Goldsmith and Mannās device was completely mechanical and used no computer program or memory. There is therefore a good case for Tennis for Two as the first video game prototype because earlier putative āfirstā video games lacked either a graphical motion display (e.g., Nim, OXO) or computing technology (e.g., the Cathode Ray Tube Amusement Device). Bragging rights regarding which invention might truly be called the first video game notwithstanding, it is notable that all of these early precursors and prototypes simulated a game or sport, and of these the graphical motion display is frequently cited as a necessary criterion for an early prototype to be called a āvideo game.ā Thus, even retrospective glances at video game history place a heavy emphasis on action and simulation as defining characteristics of video games.
Tennis for Two and its various predecessors were never widely played or released commercially; they were either produced only as working prototypes or exhibited to the public at isolated events. The first video game to find a large audience and be available beyond a single exhibition was Spacewar! Initially developed by three students at the Massachusetts Institute of Technology, Stephen R. āSlugā Russell, J. Martin Graetz, and Wayne Witanen (with help from others at later stages), in 1962, Spacewar! allowed two players to control dueling spaceships and attempt to shoot each other with torpedoes while orbiting a black hole.10Spacewar!, played using a cathode ray tube display and custom-built controllers on the Digital Equipment Corporationās PDP-1 computer, also featured a score display, a player-friendly feature not available on the oscilloscope display used by Tennis for Two. This and other competition-oriented features ensured that Spacewar! was a hit. Within a year of its 1962 demonstration at the Massachusetts Institute of Technologyās annual Science Open House in May, 1962, copies and variations of the Spacewar! program began to emerge at research laboratories across the United States, and the game was being played not only on PDP-1 computers but on other computers that used a cathode ray tube display as well.
A much more polished video game than Tennis for Two, Spacewar! might also be considered the first video game, especially as Spacewar! used digital computing hardware rather than analog technology. More relevant to the video game industry boom to come, Spacewar! was certainly the first video game to be commercialized. While the actual Spacewar! game as originally programmed could not be commercialized because it was played on expensive research computers that were usually inaccessible to the public, the first coin-operated arcade games were both adaptations of Spacewar!: Galaxy Game, a one-of-a-kind arcade unit that debuted on the Stanford University campus in Palo Alto, California in 1971 and was the first coin-operated video game, and Computer Space, a mass-produced coin-operated arcade game released later the same year throughout the United States.11 Therefore, whatever early device is credited as the first video game, thereās no debating that Spacewar! accomplished two milestones important to the scalability of the video game as a mass medium_ it was the first video game to be played on more than one machine, and the first video game to be adapted for commercialization.
While the technologies employed to create the first video game prototypes and their predecessors varied, some conceptual themes are apparent across all of these early games. Each had a basis in simulating competition, either competitive action simulations or simulations of competitive strategy games. While some of the early precursors imitated competitive board games and parlor games (OXO, chess, draughts/checkers, Nim), the prototypes most often referred to as actual video games and the first video game to evidence the mediumās commercial potential featured competitive action simulations of sport or combat (Cathode Ray Tube Amusement Device, Tennis for Two, Spacewar!). Therefore, even in the earliest roots of video games an emphasis is established on conceptual inspiration from simulation of competitive games and other competitive activities, sometimes based only ...
