Show do Milhão is the Brazilian version of the international Who Wants to Be a Millionaire format, broadcast by SBT and long associated with presenter Silvio Santos. Its correct-answer cue became one of the programme's most familiar sounds, marking the moment a contestant secured prize money and advanced to the next question. As clips and soundboards spread online, Brazilian creators began reusing the sting outside the studio, especially in quiz, trivia and reaction videos. It endures because the sound alone instantly communicates that an answer was right, without any explanation.
