Tennis for Two is a sports video game developed in 1958, which simulates a game of tennis, and was one of the first games developed in the early history of video games. American physicist William Higinbotham designed the game for display at the Brookhaven National Laboratory's annual public exhibition after learning that the government research institution's Donner Model 30 analog computer could simulate trajectories with wind resistance. He designed the game, displayed on an oscilloscope and played with two custom aluminum controllers, in a few hours, after which he and technician Robert V. Dvorak built it over three weeks. The game's visuals show a representation of a tennis court viewed from the side, and players adjust the angle of their shots with a knob on their controller and try to hit the ball over the net by pressing a button.
The game was very popular during the three-day exhibition, with players lining up to see the game, especially high school students. It was shown again the following year with a larger oscilloscope screen and a more complicated design that could simulate different gravity levels. It was then dismantled and largely forgotten until the late 1970s, when Higinbotham testified in court about the game during lawsuits between Magnavox and Ralph H. Baer over video game patents. Since then, it has been celebrated as one of the earliest video games, and Brookhaven has made recreations of the original device. Under some definitions Tennis for Two is considered the first video game, as while it did not include any technological innovations over prior games, it was the first computer game to be created purely as an entertainment product rather than for academic research or commercial technology promotion.
In 1958, American physicist William Higinbotham worked in the Brookhaven National Laboratory in Upton, New York as the head of the instrumentation division. Higinbotham had a bachelor's degree in physics from Williams College, and had previously worked as technician in the physics department at Cornell University while unsuccessfully pursuing a PhD there. He served as the head of the electronics division of the Manhattan Project from 1943 to 1945, and began working at Brookhaven in 1947, which focused on researching peaceful uses of atomic power. Once a year, the government research facility held an exhibition for the public, with one day each for high school students, college students, and the general public. The exhibition largely consisted of tours and static displays, with some attempts at making displays with "action", so for the 1958 exhibition Higinbotham decided to make an interactive display to entertain the visitors. While reading the instruction manual for one of Brookhaven's computers, a Donner Model 30 analog computer, he learned that the computer could calculate ballistic missile trajectories or a bouncing ball with wind resistance, and he decided to use this ability to form the foundation of a game. He later recalled his intentions were that "it might liven up the place to have a game that people could play, and which could convey the message that our scientific endeavors have relevance for society."
