Daily Double is a signature feature of Jeopardy, the American television quiz show created by Merv Griffin that first aired in 1964. When a player lands on a Daily Double, they can wager some or all of their score on a single clue instead of answering for a set value, which makes it one of the show's most dramatic moments. Clips of the reveal and its music have circulated widely in quiz videos, game streams, and reaction edits, where the cue signals that the stakes have jumped. Its familiarity keeps it useful, because audiences know what it means without explanation.
