The very first video game ever created. Since the definition of a "video game" is rather murky, the first video game ever created remains disputed.
Most consider the 1972 arcade hit Pong to be the very first video game, but there have been machines at least resembling a video game ever since a missile command simulator using a cathode ray tube that was created as early as 1947. The 1952 EDSAC computer game "OXO" as well as William Hoggenbotham's 1958 production "Tennis for Two" can also be considered the first, though they were played using an oscilloscope and may not have necessarily been digital raster display.
