Lol, it is true that knowing about some of this stuff could strengthen your belief in it's effect. It can either empower you or dis-empower you, the trick is to not just simply know of it, but to actually understand how it works. However, even if understood, exposure to many of the brainwashing methods should be reduced if not cut out entirely. Regardless of understanding, the alpha waves emitted by TV puts us in an unfocused and suggestible state, where we are often exposed to emotional scenarios coupled with a concept or idea they wish to implant. An emotional event + associated thoughts/beliefs strengthens the created memory , leading to it being more likely used as a point of reference when addressing relative issues in the future.
