My local newspaper is more right wing than national news. Journalists aren't magical beings that are naturally neutral. Most local news papers are pure fascist propaganda.
The concept is people would only pay for news that they want/support. Sensationalization, the Internet, MKultra level advertising and simply how information is shared but not paid for gave rise to fake news.
Now you make money lying to make more money. Why bother with the truth is nobody pays for it in an economy where you need to be paid to survive?
