Serious answer:
24 hour news is the main culprit. They have to fill those hours with something, so they talk and talk and talk, eventually talking a subject to death and boring their viewers. Additionally, instant, satellite images leave no time for reflection or even editing. All we mostly get on the really important stories is emotionally charged, muddle headed reporting on the fly, with opinions rendered (to fill the time) based upon what turns out to be faulty or incomplete information.
When the news didn't come on until 6 PM, they had time to consider things, find out more and edit their broadcast. Not so today. It's all done instantly and the amount of misinformation, or disinformation in the case of FOX, is extraordinary.
