All television programming is advertisment…

…and that high pitched whine in the signal is absolutely intentional.

Do you hear that teeth grinding, brain melting sound when you watch television? Do you ignore it? Have you in your old age lost your ability to perceive that  frequency range? If you haven’t yet become aware of it, try recording audio from a television signal and adjusting the pitch. You’ll notice it, it isn’t slightly subtle. Why, in our age of modern technology, would this be broadcast on our national video feeds? I can’t think when I hear it. I can’t pay attention to anything else. It is both mind-numbing and commanding of my attention. Is that your experience too?
