from the urban dictionary:
A process by which Mainstream Media addresses an issue incessantly, building up to a sense of pending doom. Of course, the problem, while worrisome, does not pose the grave threat they would like you to believe. Finally, MSM abandons coverage of the problem completely, moving on to another problem.
“Honey, why don’t we hear any news about the drug cartels anymore?”
“That was last month’s problem saturation, dear.”
