Without getting too much into all this myself ('cuz I'm lazy) I'm just going to highlight a few key points & provide links to elsewhere where you can get further details.
- Content of whatever it is you are actually watching, Advertising, Propaganda, and other "Programming" including subliminal content.
- The Alpha State, a light hypnotic trance-like brain wave state at the 7-14 Hz range.
- CIA Operation Paper-clip to control foreign & domestic media.
- TV Flicker rate, or Flicker Fusion Threshold.
- Psychotronic subliminal carrier technology, or the Silent Sound Spread Spectrum & the Microwave auditory effect
Such control requires the monopolization of information. That is why totalitarian states establish compulsory state schools, throttle freedom of speech and the press, broadcast propaganda, legislate the Internet, and obsessively monitor what people say to each other. They need to eliminate any competition in the ‘truth business’. And, so, those who know the 'Emperor has no clothes' are silenced by various means."~Wendy McElroy
