Early Television (Pre - through WWII)
The very earliest television sets were based off of the inventions of many other inventors and were very basically a lamp with a display. It produced a red-orange light. The transmission was only half the size of a business card. From 1935 to around 1941, the screens turned from half a postcard to a standard Letter paper size, perhaps smaller. Not many people had a television around this time. During WWII, the US experimented with TV-guided missiles, while the Germans broadcasted things from Paris.
