Channel 4 has announced there will be a second series of Humans, its most successful drama in 20 years, ahead of the show's highly anticipated season finale on Sunday night.

Set in a parallel present, Humans has prompted widespread debate about artificial intelligence. It imagines a world in which we increasingly rely on robots, marketed as high-tech luxury house appliances. As the eight-part drama has progressed, it has wrestled with questions around artificial intelligence and its possible threat to mankind, as well as exploring what it means to be human.
