>>211463710 (OP)Analog horror wasn't a coherent "thing". Mandela Catalogue was based on the conceit of taking place in a world where the media would understandably make PSA's about the entities, and where entities could also manipulate media to scare victims. It wasn't conceived of as some new thing, it was just an online collection of horror videos.
Before Mandella Catalogue there was the channel 5 stuff, again, completely contextualized as fictional PSA's. They played on the strengths of that aesthetic, but they made sense. Notably, the early channel 5 type stuff often had some kind of satirical point or slant, like the one telling Americans to commit mass suicide. There was coherent artistic vision and intention.
People liked certain elements of the vibe of both of these starting points, the aesthetic of all those, so they wanted to crib it for basically any concept they had for an online horror short or series, regardless of how applicable it was. It became basically a filter, a flavouring they slapped on top of a concept regardless of whether it made in universe sense or enhanced it. Either that or they made stuff that was entirely derivative with absolutely no slant or differentiation, except in the sense of being way more generic without the satirical or subversive element channel 5 sometimes does.
It shouldn't be thought of as "what happened to analogue horror". "Analogue horror" should never have been conceptualized as such.
