>>80182234My guess would be her EU viewers are older on average simply due to the fact that English for most people here is the 2nd language and, unless you are commited/talented, it takes a while to learn it properly.
And since I know the question was about time slot – EU has probably a lot of collage aged people. They don't need to get up early for school like teens (at least not always) and they still have far more time on their hands than working people. Though this is just an uneducated guess
