50 Grand Slam is a game show from Ralph Andrews Productions that aired on NBC from October 4 to December 31, 1976.
Tom Kennedy hosted the show (although Peter Haskell served as emcee for the unaired pilot), with John Harlan as the announcer.
The current champion, or the winner of a coin toss, decided whether to play first or second; while the first player heard the question and answered it, the second would be placed in an isolation booth.
Although primarily a quiz show, there were occasional digressions; for example, on the premiere episode two contestants playing in a golf category, in lieu of answering questions, were asked to make a specific shot on a miniature driving range that had been set up in the studio.
The premiere and finale of 50 Grand Slam are known to exist as off-air recordings among collectors and traders of television game shows, while the pilot and an episode with a $50,000 win also survive.
