Since trivia is banned why do we allow questions like "What was the first/most X", "Who was the first/most X to do X" on the cinema-history tag? It seems to me that those will be questions will invariably be trivia in nature.
A recent popular example is this question about the "First Movie." That is pure trivia, and would easily fit on any trivia game/show.
Fall under application or analysis rather than plain trivia.
That seems like a good litmus test to me.
