It's almost like teens discovered a new secret code to communicate with each other right in front of adults. I loathe the next developments. Imagine if teens expand this concept so devices can be controlled to vary amplitude/intensity and frequency.
- multiple choice exams: I know this item isn't TV-related, but I'm concerned as an educator. Just imagine having some student in the back of the classroom type the number of the question on a cell phone keypad, followed by the '#' key. Then the student chooses the letter for the correct answer and hits the '#' key again. That student's phone 'announces' the correct answer so that only students can hear the announcement.
- subaduliminal TV messages: Subliminal means below everybody's level of conscious awareness. Subaduliminal? That's just below the level of conscious awareness of adults. (That's the best word I can make up.) Imagine TV commercials that use these higher-pitched sounds to speak directly to your child without your knowledge or permission, even though you're sitting in the same room.
Paranoid? You bet.
