A lot of the stuff I watch are not made by a man in his shed. In fact, a lot of the big channels are not "user generated", they are made by a team of people.
For example Sky Sports and TNT Sports shows all the goals from PL and CL matches minutes after the game ends. Very fast turn around for the highlights. This is not user generated content.
I also watch clips segments from US shows like Seth Meyers or The Late Show, which are network TV from America. Then there are the "user generated" stuff like LTT which have 100 employees. Even down to the REAL single man channels like movie reviews...what difference does it make if the movie review is by one man in his basement vs a critic like Mark Kermode? Mark Kermode films his stuff with a webcam now in his spare room half the time. He has left the BBC to do his own stuff.
YouTube hasn't been merely user generated for a long time now.
