They also have a series of shorter progrogrammes following the creation of an object, again without narration, under the "Handmade" series.
All great ambient slow TV.
Friends is the same way. Much of the hubbub over its becoming big again when Netflix won the rights a few years ago was from young women discovering the show, but I suspect that just as many of the viewers were slightly older women who've seen every episode multiple times and put it on in the background while going about their day.
I've always viewed it as something as simple as background noise, but I know TONS of people who do this (myself included), so I imagine there's probably a much deeper phenomena at play
For example, my girlfriend experiences tinnitus, so having a completely silent house is annoying to her, since she just hears a high pitched noise instead of silence. But if you use ambient TV to avoid getting lost in your own thoughts because of fear of where they might take you, or if you use it as a stand-in to avoid feelings of loneliness for actual human company/conversation, then that is where I see it as unhealthy.
Instead, this sounds more like what my girlfriend uses "The Office" as: TV that you're so comfortable with you like to have it on when you're doing other things and not actually watching TV.
Personally, I think it's some kind of avoidance behavior and not something that should be encouraged. I'll admit I haven't read the article though, because I am constitutionally opposed to learning about shows that show Americans going to Paris and wearing berets.
