Well, the first thing that you have to do is decide if you actually want to stop it.
All life is guided by the Perception of Hope and Threat. The Media is the Perception Matrix (featured in the film The Matrix) presented as a Gordian Knot, wherein every strand of deception merely wraps around to another. One of the oldest questions of Man is how to avoid deception, how to untie the Gordian Knot of deceit.
But there is a serious question to be answered before you even try. A great many powerful people are vested in the Matrix of beliefs and deceits. Not everyone wants to take “the red pill”. They would prefer not only to remain in the Matrix, but also to keep the Matrix strong and populated. So do you really want to become an outsider to it? Do You want to “take the red pill”.
Before the Propaganda Ministry (aka Media) changes their tactics, they have to be given a reason. They have to perceive the hope in communicating the truth and the threat of deceiving. Typically since lies work for at least a while to escape judgment and/or gain profit, people have to be brought into serious need before they give up their hope in deceptions. They have to perceive a threat greater than their former hope or a different hope greater than their former hope (an even greater means to get rich and powerful). They have to give up on the impetus for their ego, their religion, their golden calf, their protected beliefs in what they are and what they do.
But my take on it is this;
On the planet of the apes, in the land of lies, all they do, to their own demise.
Medications/drugs, Media/entertainment, and Money are actually all the same thing, a medium used to keep your mind and heart trapped within a gilded cage, a solipsist fantasy world wherein you work, suffer, and die as a slave at the bequest of The System, The Matrix.
But to get out of it is like a heroin addict surrounded by heroin addicts trying to be the only one clean - what are the chances? And what is actually to be gained by you individually? How many of those people all around you are still going to be your friends? How many are going to suddenly hate you? The deceivers do all they can do to control all belief so as to hide the truth. They can’t tolerate hints of light in the darkness.
So before you even try, decide if you really want to try, decide; “red pill or blue pill”.
