The Doctor Who theme is one of television's most recognisable pieces of music. It was created for the BBC series Doctor Who, which first aired in 1963, with the theme written by Ron Grainer and its groundbreaking electronic realization produced by Delia Derbyshire at the BBC Radiophonic Workshop. Its unusual sound helped define the show's identity from the start. The tune remains popular in fan edits, convention videos and meme-style posts because a few seconds instantly suggest sci-fi mystery, travel through time and classic British television.
