The experiment has also been brought to the 21st century and its video and audio codecs: https://www.youtube.com/watch?v=icruGcSsPp0 - uploading a video 1000 times to YouTube.
reminds me of the old days of 4 track recording where you'd bounce 3 channels down to one, rerecord, bounce again. lather rinse repeat. by the time you got to the 3 or so round (depending on the quality of the tape) it would be pretty gnarly.
back when i worked in a VHS dubbing facility, we'd get bored and do stupid stuff like this taking a master to VHS, then using the VHS as a master to make dub of dub of dub. after the 8th dub, it was pretty trash. Similarly, we'd take a video in -> video out to another VCR -> video out cascading down until the original signal to the video in of the last VCR was trash. (the place was wired correctly with proper video DAs. we did this because it was 3rd shift and no supervision)
This brings back memories of art school, a friend recorded themselves running up and down a hill and made many copies of copies of the video on VHS. They displayed different generations of the degrading video side by side on a bank of monitors.
