Description
The cathode-ray tube amusement device is the earliest-known concept for an interactive electronic game, as well as the first game concept to incorporate an electronic display. As described, the device would simulate an artillery shell arcing towards targets on a cathode-ray tube (CRT) screen, which is controlled by the player by adjusting knobs to change the trajectory of a CRT beam spot on the display in order to reach plastic targets overlaid on the screen.
