Propaganda doesn't have to be as blatantly overt as a film by Josef Goebbels or Michael Moore.
The dictionary tells us that propaganda is information of a biased or one-sided nature, usually casting some subject in a negative light. It can be outright lies, or it can be lies by omission. But the thesaurus also lists "advertising" as a synonym.
Many advertisements flash by us each day, most having little effect on us. Here is one that flashed by me the other day, but I reached out and grabbed it, analyst that I am.
What is the purpose of the above ad? What is the bank trying to achieve? Is it propaganda? Do you think the bank is truly "committed" to our military and wants to give them a warm and personal banking experience? Do you think the fact that the family in the picture is black is coincidental? Does this ad persuade you that this big bank is really caring and gives individual attention to all their customers? Does it make you want to do business with them? Vomit at their insulting patronizing? What?
