The original theme to Jeopardy! (from '64-'75) was called "Take Ten" by Julann Griffin (Merv's then wife who originally came up with the show's format).

Starring Art Fleming, Jeopardy was on the NBC daytime schedule from 1964-1975, returning in 1978 for another season.

In the 1978 version, only one contestant went on to the Final Jeopardy round. Other than that, the show has stayed pretty much the same as the current syndicated version, now hosted by Alex Trebek (High Rollers).

I was at a Hollywood party one night in 1984, and one of the producers of the new Jeopardy and I were talking. I asked him why they were using Alex Trebek instead of Art Fleming. He told me that Fleming was too old, and they had plans for Jeopardy to run for a long, long time. I informed him the show would never last, it was too intellectual for modern audiences and people would miss Art Fleming too much - he WAS Jeopardy! Guess I told him...
