Jeopardy is a great TV Show!
I agree!  I love to listen to the audiobook that is voiced by Trebek!  It features the "behind the scenes" material 
Oh I had no idea there was an audiobook about it, how interesting!
I've been watching Jeopardy since it debuted on NBC on March 30, 1964!  That's a long time ago!
Oh wow, yes it is. Has Trebek always been the host on there?
No - at one time it was hosted by Art Fleming, and aired at 11:30 a.m.
Oh, so when did the change in hosts happen?
I really don't know!  The original daytime version aired until January 3, 1975
Ah I see, that's probably when the switch was made. Is the show still running?
Yes, and the current version premiered on September 10, 1984
