But we can see from the show's lack of success that enough viewers didn't like it, regardless. Maybe they found it tedious in a pre-WWTBAM time where no shows hung on any one question for that long. Maybe the material was TOO esoteric for the audience, lending to a "who cares?" vibe.
To be fair, enough viewers also didn't like the more traditional Q&A rounds when the show switched to those.
If we're trying to pinpoint why
Trivia Trap failed, there are plenty of reasons, and probably more than one of them are correct. I could point out the show's formidable competition in that time slot or the fact that pure trivia before noon is a tough sell in general.
But seeing as
Trivia Trap failed equally quickly on Buzzr, my best guess is that a trivia game show needs something more than just Q&A to succeed.
Jeopardy! has categorization and rapid-fire material;
Millionaire has high stakes. I agree that "eliminate wrong answers" was the better format and the better chance the show had to survive, but without speed or high stakes, it isn't engaging enough.
