It was untargeted multicast with no back channel for comments/feedback. This is the diametric opposite of Facebook or Twitter which are all about soliciting and encouraging as much back channel communication as possible, and feature content heavily curated to your particular interests to make it more of a dopamine hit than your average America’s Funniest Home Video watching session.

And here’s another difference: at least in my country, this programme was something that might be shown for an hour, maybe each day or maybe each week (it’s been a while, I don’t remember which one it was). There wasn’t a 24/7 channel that would show a steady stream of such videos without a pause - in other words, the show started, and ended. Twitter and Facebook never end.
