EastEnders first aired on BBC One in 1985, created by Julia Smith and Tony Holland, and its theme was composed by Simon May. The music became inseparable from the show's famous cliffhanger endings, often called doof doofs after the drum beats in the closing version. Online, creators borrow the sting much like the Law and Order DUN DUN to signal a dramatic twist without any explanation. Its long run in British popular culture means even viewers who never watch the soap recognise the cue instantly and understand the joke.
