Who Wants to Be a Millionaire began as a British television quiz show in 1998, where contestants answered increasingly difficult questions for a top prize of one million pounds. Its dramatic musical identity, including the opening theme, became closely tied to the format as the show was adapted in countries around the world, including a hugely popular American version. Because the format is still recognised instantly, creators reuse the intro to signal a quiz, a high-stakes decision or a moment of suspense, even in short videos far removed from television.
