propaganda campaign, n.All

A Propaganda campaign (n.) runs ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠on a useful frame and repetition: other frames are ignored, facts are picked to fit, and when the case collapses the story is simply dropped.

A Propaganda campaign (n.) runs ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠in one direction only: it needs the mass media's collaboration, and the filters let any story that hurts large interests peter out, if it surfaces at all.
