Horizon is a long-running BBC popular science and history documentary programme, notable for coining the term supervolcano. Some episodes are adapted from documentaries by other broadcasters such as PBS's Nova, and episodes of Horizon are in turn adapted by other broadcasters around the world.

It has often been accused of dumbing down, with one former editor writing a newspaper article about how the programme concentrates too much on human stories, and not enough on the science. [1]
