Cathode ray tube amusement device

Doing a new blogging series. Every Monday I’ll be uploading one.

Did you know the first ever interactive electronic game was invented in 1947?

   It was invented on a Cathode Ray Tube by Thomas T. Goldsmith Jr. and Estle Ray Mann. The game was simple enough, It was a missile simulator inspired by the displays in the radars during World War II. Since graphics could not be drawn at the time, the game used screen overlays as targets, which worked well either way. The game used “Analog Circuitry” instead of digital, to control the CRT beam and position a dot on the screen. Seems fun, right?

The patent was filed on January 25, 1947 and issued on December 14, 1948
