Well I was hoping this thread would be more about the things we did socially, or practically. But since you can’t seem to grasp that concept, I suppose we can bend the rules a bit for you anal folks out there.
OK, my mistake, I should have been more concise in the OP. Actually the devices mentioned WERE invented in the late 60s. I should have said something like “Habits and devices that were popular in the late 60s that still survive today”.
There was an interesting article on the last page of American Heritage Magazine of Science and Invention several years ago. It showed a picture of the very first “Pong” game, and the article was by the guy who built it.
In the late 1950s.
They evidently put it together using an oscilloscope and lots of electronics at Bell Labs. It was incredibly popular.
I don’t know if it’s really the direct ancestor of the arcade “Pong” that came out in the late 1970s (I doubt it), but it would predate Space War, depending on your definitions, of course.
I think I mentioned florescent colors, I’m not sure if that covers day-glo or not. I was thinking about the black light too. I would say black light posters are very rare these days (put them on the failure list), but you do see some black lights in bars once in awhile.
