in the 80s and mid-90s, there was a Seagrams-esque building in Nashville that would put up holiday and civic messages with letters made by leaving certain office's lights on all night.

I don't know if they stole the idea or not, but it pre-dated any of the ones I'd seen IRL or on the internet by quite a while.
