You Tube has a whole genre of US-based You Tubers being filmed reacting to pretty much anything: the British royal family, Harry & Meghan, British comedy like Monty Python and Dick Emery, you name it.
If you analyse the number of views, they do seem to go up significantly when the You Tuber focuses on showing clips of and talking about the cultural phenomenon that is Harry/Meghan and reactions to them.
I've watched a bit of the output from Dylan 'Winning Communication; Jen Real Housewife; the Sidley Twins; HG Tudor; Proper Wiseguy; the Royal Rogue; PDina; Beebs Kelley; and watched many videos from Lost Beyond Pluto (and the Plutonium Show) from Australia. Pluto is head and shoulders above the rest, IMO.
These videos can seem pretty repetitive. I've said this before on another thread, but I think they jumped the shark when they started interviewing each other, and I suspect a few of them move among us, getting ideas for content - as do a couple of Mail journalists that I haven't mentioned.
However, the You Tubers do seem to be sent or able to unearth archive clips and photos that are of cultural interest, so there's that I suppose.
This board is also the home of paid saccharorum, I suspect.
