@kreppyfazta: Tennis for Two was designed by American physicist William Higinbotham in 1958 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. The game was displayed on an oscilloscope and played with two custom aluminum controllers. An oscilloscope is a type of electronic test instrument that graphically displays varying voltages of one or more signals as a function of time. #tennisfortwo #firstvideogame #videogames #game #invention
