Planet Earth is a television and film documentary franchise produced and broadcast by the BBC. The franchise began in 2001 with the success of The Blue Planet. As of 2017, The Blue Planet has spawned 5 series and one feature film.
In 2001 the BBC broadcast The Blue Planet, a landmark series on the natural history of the world's oceans. It received critical acclaim, high viewing figures, audience appreciation ratings, and many awards. It also became a hugely profitable global brand, eventually being sold to 150 countries worldwide. Feedback showed that audiences particularly liked the epic scale, the scenes of new and unusual species and the cinematic quality of the series. Programme commissioners were keen for a follow-up, so Alastair Fothergill decided that the Natural History Unit should repeat the formula with a series looking at the whole planet. The idea for Planet Earth was born, and the series was commissioned by Lorraine Heggessey, then Controller of BBC One, in January 2002.
A feature film version of Planet Earth was commissioned alongside the television series, repeating the successful model established with The Blue Planet and its companion film, Deep Blue. Earth was released around the world from 2007 to 2009. There was also another accompanying television series, Planet Earth: The Future, which looked at the environmental problems facing some of the species and habitats featured in the main series in more detail.
