It only really made sense as a way to give slides meant for human viewing, computerized data for sorting, filling, or otherwise using simultaneously with the slide. Like, a picture of an engineering diagram, patent, survey site, military target, etc.
Before we could store a picture as raw binary data, this was an interesting way to fill the need to digitally notate images. Punch cards like this were definitely in use for a while. I have a post above with an image.



That’s really cool. That was the 90s wasn’t it? I think I remember reading something about that in 2600. Cool though it may be, it’s just the same delay-line memory, but using the Internet as a medium rather than a drum of mercury. Which echoes what I was saying. I agree with you that creativity is not lacking now. I was just musing on how it’s mostly mapped off the map now rather than the territory.
