A closer look

Before we had Black Mirror making us terrified of our toasters, the BBC was already traumatizing a few dozen rich Londoners with a live broadcast of Karel Čapek's R.U.R. in 1937. Because this was the absolute dawn of television, nobody bothered to invent a way to record it yet. So, the first televised sci-fi robot rebellion vanished into the ether the moment it aired, leaving us with zero footage of actors in tin foil pretending to crush humanity.
