Originally composed by Jeopardy creator Merv Griffin, the piece known as Think has accompanied the American quiz show since its revival in 1984. It was written for the Final Jeopardy round, giving contestants thirty seconds to write their responses while the audience waited. The tune became one of television's most recognised themes, quoted and parodied across sitcoms, adverts and online videos. Like the Law and Order DUN DUN sting, it now functions as shorthand, instantly signalling a dramatic pause or a pending answer even to viewers who have never watched a full episode.
