I’m Scottish but moved down to Sussex as a kid and have been here for almost 3 decades. I’ve never heard of it either. Seems a generational thing as both my parents were familiar with it as an old dish.
I can’t vouch for Samsung but Vizio have said in the past that they make very little profit off their TVs and this is offset by data that is collected from usage.
Now I’d imagine that Samsung are making a hefty profit on the 75” 4K all singing sets (and still spying on you) but the cheaper ones seem to be priced so there isn’t much profit.
I flew upstairs in a BA 747 to Tokyo. Was business class. It was a bit better than my return flight downstairs in business class as there were only 20 seats and 2 crew between us so better service.
