Every reference I can find says the Alex Trebek "Jeopardy!" premiered on September 17, 1984.
But I have a copy of the September 8-14, 1984 TV Guide, Cincinnati edition, that shows "Jeopardy!" airing on Channel 9 in Cincy and Channel 22 in Dayton at 7:30 P.M. that week. And among the Monday, September 10, listings, there's a Channel 22 ad promoting the premiere of "Jeopardy!" and the fact that it's back-to-back with "Wheel."
So...did TV Guide screw up, did both WCPO and WKEF screw up when submitting their listings and ads, was the "Jeopardy!" premiere pushed back a week after the TV Guide deadline, or are the EoTVGS and Harry Eisenberg's book, among other sources, wrong about the premiere date? I assume "Jeopardy!" was being distributed via satellite from the beginning, so surely it didn't premiere on different dates in different cities!
