Jeopardy is the long-running American quiz show created by Merv Griffin, first airing in 1964 and later becoming a television staple during Alex Trebek's tenure as host from 1984 to 2020. Its time's up buzzer became familiar from rounds where contestants had only seconds to respond in the form of a question. Online, creators paired it with the opposite correct answer gameshow sound to build game show parodies, then began using the buzzer alone for any late, missed or expired moment in everyday edits.
