The syndicated television game show "Jeopardy!" has used the tune "Think!" as its theme music since 1984. The tune is one of several used by the show throughout its history.
"Think!", along with other tunes used as theme music on "Jeopardy!", was written by the show's creator Merv Griffith. "Think!" has become particularly iconic and popular, and has been used in many contexts outside the game show, including sporting events and weddings. Griffith claimed that licensing of the song had earned him over $70 million in royalties. He originally composed the song as "A Time for Tony," and it was a lullaby for his son.
