Most episodes of this series are lost. This was due to NBC's network policy at the time where the master tapes of game shows because they saw no value in keeping the tapes intact for reruns since most game shows were not rerun after they aired. Thus, the network saw no reason to preserve the tapes. Only a small number of episodes of the show survive.
The show's set was recreated for the music video of 'Weird Al' Yankovic: I Lost on Jeopardy (1984) (A parody of Greg Kihn Band: Jeopardy (1983)) with Art Fleming and Don Pardo. Rumors also abound that this video helped inspire the reboot of Jeopardy! (1984) that launched in the fall of that year, the 20th anniversary of this original version.
When it came time to choose the show's host, the only choice was Art Fleming. Merv Griffin saw Art in a TWA commercial and thought he seemed authoritative, yet warm and interesting. Griffin and company called Art's agent and although Art had never done game-show work, he was interested. He came in, tried out, and was the unanimous choice for host, a position he held 2,753 shows on NBC.
The best-known song on Jeopardy! is "Think!", originally composed by Merv Griffin. "Think!" has always been used for the 30-second period in Final Jeopardy! when the contestants write down their responses. According to Merv's son Tony Griffin, while out to dinner with his wife Julann Griffin, Merv wrote the Jeopardy! "Think!" music in a minute and thirty seconds. Merv said the song is just as famous as "Happy Birthday" and has estimated that the use of "Think!" had earned him royalties of over $70 million throughout his lifetime.
Burns Cameron was the largest winner of this version of Jeopardy!, winning a total of $11,110 between his five-day stint and the 1965 annual tournament of champions. Burns was also asked to come back for the show's ceremonial 2000th episode and this time played for charity. He was later invited to compete on the summer invitational tournament, Super Jeopardy! (1990), as the only contestant of this era invited to compete.
