"Propaganda"...that's brings back memories.
I remember when it used to be called propaganda. Now they have all these cool new euphemisms, all steam-lined for the 21st century. Like, "fake news", "misinformation", "disinformation", "viral sloganeering", and my favorite, "alternate facts". It's almost like they don't EVER want to use the word "propaganda".
For those looking for more information on propaganda, may I suggest "Propaganda" by Edward Bernays.
