In 1940, the Federal Communications Commission got its first demonstration of FM radio by Major Edwin H. Armstrong.
Another inventor, Lee DeForest, challenged Armstrong’s priority for this discovery and the issue was twice argued before the US Supreme Court—which found in DeForest’s favor. However, the scientific community has always credited Armstrong for the invention and he received a gold medal for it from the Institute of Radio Engineers.

The Mercury and Gemini programs had put Americans into Earth orbit. Apollo had been to the moon. But NASA wanted a reusable rocket ship to explore Earth orbit and to supply and staff a space station.
