Jeopardy is the long-running American television quiz show created by Merv Griffin, first broadcast in 1964 and relaunched in syndication in 1984. Its thinking music, titled Think, was composed by Griffin and became famous as the 30-second countdown during Final Jeopardy. Decades of daily broadcasts made the tune shorthand for mentally searching for an answer. Online, creators lifted the main section as a standalone meme sound for waiting rooms, trivia edits and reaction videos, where it still signals time is running out.
