The old metric used by free-to-air networks was advertising minutes per broadcast hour. When I stopped watching FTA about a decade ago that number was about 12 or 13. Youtube’s must be 40+. I’m not brave enough to rawdog 60 minutes of YT and test it (and of course it wouldn’t be uniform number anyway)
Anglophone country but I would rather not specify.
Yes the BBC has its own legacy wierdness - and sadly a track record of protecting predators in order to protect itself
