Are "reality TV" programmes such as The Apprentice, Big Brother, Faking it, I'm a celebrity etc. fixed and scripted? With my cynical head on, sometimes it looks as if the producers have decided who will win before filming even starts. I've heard that in Jeremy Kyle, the producers lie to the guests about the starting time: they suddenly appear two hours early to drag them to the studio, so that they don't have time to make themselves look nice, and they look dishevelled as befitting the Mail stereotypes.
With some modern TV programmes, such as the newer Crystal Maze, is it a thing for the presenter to actually acknowledge it's not as real as it looks, e.g. for Richard to say "she'll look different as she goes through the door, it's called editing" (and then she appears in full safety gear).
