¿Quién quiere ser millonario? is the Spanish title used for local versions of the Who Wants to Be a Millionaire? television format, a franchise that became widely recognizable in the late 1990s and 2000s. Short clips tied to the show spread online because its tense quiz-show atmosphere is instantly understood, even out of context. People still use the audio in memes, trivia edits and joke reveals when they want to frame a simple question as if a life-changing prize depends on the answer.
