So I probably watched this in the late 2000's, it was a show that I believe was broadcast on Adult Swim but I think had a Channel 4 (UK) logo at the start and end. It kind of had a similar ethereal feels to Garth Marenghis Darkplace, which definitely also had a Channel 4 logo at the start.

If I remember right, each episode was themed around a certain topic, and the episodes would start out normal and get progressively weirder. I honestly can't remember much about it in detail other than the presenters were British (I believe it was a man and a woman), and I think a lot of the set design was a white background where they'd show random things related to the topic. The style of the show was designed to look like it was from the 70's or 80's.

I wasn't able to find anything by googling with these terms but I'd love if someone knew what I was talking about. Planning on making a VHS tape with all of the episodes, probably a double feature with Darkplace.
