In 2005 I came across of video stream (mp4? viewable in VLC) of early 20th c. cartoons. There were dozens and dozens of them and nothing else. I never worked out who was behind it, just that it's IP was in western Europe. It was up for at least a year.

My kids were often with me during adult hours (work, etc) and I'd put it on for them. But I was also half-captivated by the idea of anonymously delivered content.

It would be fantastic to find a modern equivalent except delivering an endless slate of novel, off-kilter and largely inexplicable content.

Sometimes TikTok live streams are like that. Not always, but at certain times of day, there's a huge variety. For me, I interact with it like an old television. Just flipping channels. Not knowing what I'll get and not seeking out specific live streams. At 3 AM my time, I stumble across weirdness and it feels like my childhood watching random stuff on cable.

Take a look at archive.org’s video section.
