This gem gets right to the heart of "Gaslighting."
The twist is that these media groups seem to be doing it to themselves.
For those unfamiliar with the term, per wikipedia.com:
"Gaslighting is a form of manipulation that seeks to sow seeds of doubt in a targeted individual or members of a group, hoping to make targets question their own memory, perception, and sanity. Using persistent denial, misdirection, contradiction, and lying, it attempts to destabilize the target and delegitimize the target's belief.
Instances may range from the denial by an abuser that previous abusive incidents ever occurred up to the staging of bizarre events by the abuser with the intention of disorienting the victim. The term owes its origin to a 1938 play Gas Light and its 1944 film adaptation. It has been used in clinical and research literature, as well as in political commentary."
The term originates from the 1938 stage play Gas Light in which a woman's perception of reality is destroyed.
