Tennis for Two draws a crowd at Brookhaven

What happened

William Higinbotham, head of the Instrumentation Division at Brookhaven National Laboratory on Long Island and formerly a designer of wartime radar displays, built a two-player tennis game to entertain visitors at the lab's 1958 open house. Working with technicians David Potter and Robert Dvorak, he wired a small analog computer to an oscilloscope, showing a side-on view of a court, net, and bouncing ball on a five-inch screen, with players using separate box controllers to set the ball's angle and timing. It debuted on 18 October 1958 and drew long lines; Higinbotham never patented it, later saying it seemed no more novel than the bouncing-ball demonstration circuit in the computer's own instruction manual.

How we know

Brookhaven National Laboratory, the U.S. Department of Energy lab where the game was built, published its own institutional history of the project, including the 1958 debut date, the blueprints still held by the lab, and quotes from Higinbotham's later depositions and from colleague David Potter.
