Fake News, despite all the fuss, is not a recent phenomenon.
In my day, it was more commonly known as propaganda.
For as long as I can remember, reporting of fake or false news has been popular, including gain for political reasons, to make money or sway popular opinion.
Many years ago, I was taught in school to question everything and not believe anything without a balanced view (a number of sources).
Do your research on the subjects that matter to you.
