The theme tune to British science fiction drama Doctor Who has been declared the best sci-fi tune of all time.
The music was composed by Australian-born Ron Grainer when Doctor Who first aired in 1963 and was arranged by Delia Derbyshire.
Derbyshire produced the iconic theme tune by combining a tape loop of a struck piano string with the sound of test oscillators and filters. The current version is arranged by Murray Gold.
Red Dwarf, starring Chris Barrie and Craig Charles, came in second place, while The X-Files, starring David Duchovny and Gillian Anderson, rounded out the top three.
