The episode was posted to the game show's YouTube channel in honor of its 58th anniversary. "Watching the 1964 pilot, it’s incredible how little has changed," says Matthew Gault. "The basics of the show are all there. Original host Art Flemming mugs for the camera while leading three contestants through the pressure or answering trivia in the form of a question. Even the music for final Jeopardy! is the same."

Very g00d!!

I did see the original Jeopardy pilot and though the set and some of the sound effects were different from what we would eventually see from the Art Fleming hosted version, it would impress NBC officials and it went on to an 11 year run.
