Sometimes you'll just come up with a question, maybe even one you've had for a while but suddenly decided, damn I need to know the answer to that one, it's got to have an interesting history.
Put simply, I want to know what the first installed use of an electronic bitmap sign. This means any large format, think Times Square size, display which utilizes a grid of lights (or non-illuminating active elements), to automatically display information (text).
Now Wikipedia proclaims the first *computerized* sign ever installed was the famous Westinghouse Sign. How computerized it actually was I believe it still up for minor debate, but regardless, Wikipedia claims this was completed in 1967, and construction was first initiated in 1966. Now that might be good enough, except just today I was watching some Beatles music videos on YouTube. In particular, I was watching the Vevo music video for Eight Days a Week, which has footage of the Beatles' concert in Shea Stadium.
https://youtu.be/kle2xHhRHg4?t=107If you were to pause this video at around 1:46 and 1:47, you can see in soft focus, quite obviously, a bitmap text display in the background. Now I wouldn't say a bitmap screen must be computerized, so the Westinghouse Sign may have genuinely had a "computer" on it, with these signs simply having some other sort of controller logic, but that still leaves the original question. If this concert happened in 1965, and as of that point Shea Stadium had a large format bitmap sign, what was the first large format bitmap sign?
Any ideas or insight would be helpful. I've tried to Google, but this question is particularly strange in that it seems like something someone should know, but I can't find that specific information documented anywhere. That being said, I haven't researched too hard, and thought I'd try here before digging through patents and such.
