A couple of months before Rafferty's version premiered,
Broadcasting magazine mentioned the return, and that the original got respectable ratings. But I guess it wasn't enough to beat whatever sitcom reruns CBS aired at 10:30 (
Alice?
The Jeffersons?). IIRC, ABC gave that time to the affiliates.
Never mind. I found
the article. The cancellation was the result of NBC genius idea to move
Texas to mornings.
NBC's new entry at 10:30 a.m., Blockbusters, ran on the NBC schedule from October 1980 to April 1982. [Brian Frons, VP of NBC daytime] said it was canceled originally not because of its performance, but because the network had no place to put it when it decided to try the soap, Texas (subsequently canceled), in the morning. That game show "was averaging a 17 or 18 share with a horrible lead-in," the old Regis Philbin Show, said Frons. Blockbusters is a question-and-answer game show
which the network hopes will prove compatible with Wheel of Fortune, which airs at 11 a.m. In hindsight, said Frons, Blockbusters "probably should have never been taken off.
Moot point nearly 38 years later, but why NBC didn't just replace Regis with
Blockbusters, we'll never know.
I want to argue that you had to follow the visual action to see which contestant landed where on the board, thus making it a bit more complex for someone at home simply listening. But so many other games involve similar strategies and did just fine (
Wheel, Hollywood Squares, TTD come to mind).
