Adolf Hitler did exactly the same thing. In fact much of what he did is happening all over again. I recommend you study Hitler's methods. He was a master propagandist. If you do this you will see the same methods used everywhere.
Television is the most successful medium of manipulation ever.
Its news bulletins put a spin on the stories to suit those in control. Television series and movies are used to condition people to view the world in a certain way, or prepare them for upcoming events. When independent information contradicts the world view presented on television, most people will rejected it in favour of the 'accepted' world view. Control of mass media has led to a highly suggestible population. Most of the media is owned by a few corporations and the presentations are slanted in line with company policy.
