Additional observation: it's also interesting to me that the term seems to be having a resurgence of late?

It started out largely being an accusatory term used by the American political left to disparage biased and/or incorrect information spread by Trump supporters (mostly, anyway). But then Trump and his supporters decided two could play at that game, and it became almost exclusively a term used by the Trump/Fox News crowd to bash the left.

As a result, the left stopped using it as quickly as they had started, and the term all but disappeared from respectable news sources.

Now, a year and change later, it seems to be coming back.

No point here other than it's fascinating how trends in culture stop, start, and change with time.
