That and the gentle recaps they often have built in. In the UK when we air US TV shows they often seem really weird because when there would be an advert break in the US parts of the story and sometimes even lines are repeated by the actors to help you get back into it. Sometimes you get a cliffhanger line, a sort of a second's pause, and then the cliffhanger line repeated in a different tone! Where we don't have advert breaks this comes across as bizarre until you think the US would put an advert there, and you get the same kind of thing but across episodes on Netflix.
