Chekhov's News

The protagonists turns on the TV, listen to the radio, or skim the newspaper as part of a morning routine and we get some brief look at the big news, then some background noise small articles and local goings-on. Of course, by the Law of Conservation of Detail, it's never really very small; even the most mundane or seemingly faraway events crash into the here and now with dramatic results.

That article about a new building opening? It will house the Doomsday Device MacGuffin. Reporter mentions sudden disappearance of a species? They're actually aliens going home. Radio announcement of an author cancelling his book tour? He's been silenced by the Brotherhood of Ancient Conspirators. Whatever the seemingly small-fry buzz, it may appear irrelevant or incidental right now but will turn out to be critical to the resolution of the plot.

Contrast Ignored Vital News Reports, in which the importance of a news item is obvious to the audience but the characters ignore it. This does not include news items that are purely Foreshadowing; to be Chekhov's News, the news must appear early on without obvious significance, and the payoff has to appear later in the work.
