The television it self has a flash rate that entrains your brain into into a hyperactive state until it becomes fatigued and enters into a theta wave pattern which is what your brain enters into while in a dream state. Because of this brain wave entrainment your mind is in a state of passive absorption under which the normal categorizing, skeptical, censoring part of your brain that would normally classify information according to validity, usefulness, and association is completely bypassed allowing information to enter directly into your permanent memory with no frame of reference. How many times have you been watching a television program in a dazed slack jawed state, then a commercial pops up and you forget what you were even watching? This is your brain falling out of the fatigued theta pattern, giving you a moment of consciousness you were previously not enjoying.
This results in a state known as "source amnesia" where you have this information in your brain, but you can not determine the source. Was it a conversation you had, a book you read, a show you watched, a dream? This is the primary mechanism and strength of Television "soft" mind control. I refer to this as "soft" mind control to distinguish from programs like MKUltra which are described as "hard" mind control because it is basically using chemicals and brute force repetition to gain results as opposed to an unrelenting but more casual form like TV mind control.
