Facebook Watch
(launched in 2017; defunct 2023)
IMDb; official website; Wikipedia

Of course I've seen some videos on Facebook, without actually going to its "Watch" section. And I have no idea if any of it was actually part of "Watch," or just something that some Facebook page I might follow uploaded to their own wall or channel, or whatever. It confuses me. But there are some things I know are part of this service. I might want to check out Sorry for Your Loss, and Limetown. Plus some series from Crypt TV, including "Kinderfanger", and "Mira Mira".

stuff I've seen:
The Birch
Stereoscope
Woman in the Book
