Rand Simberg mentions that color TV is 50 years old today.
Color TV was invented at RCA. My father was a patent attorney at RCA (although not at that time) and liked to tell a story that had made the rounds there about the development of color.
The develpment procedure involved a team in one room operating a camera aimed at a bowl of fruit on a table, and a second team in another room receiving the signal from the camera. Halfway through the testing, the camera operators painted the banana in the fruitbowl blue. After much consternation on the signal receiving team, they called the camera team on the phone and told them that the banana looked great, but everything else was horrible.
