It gets harder and harder to capture your attention. The competition is fierce, funny, and shocking.
In the future, folks strolling through public areas will be hit with pop-up holograms advertising products. They'll be suddenly, and unexpectedly, confronting a catchy spiel from a supermodel or popular athlete who is close enough to touch. Given that collision avoidance technology will be so robust by this point, these pop ups will even bombard us as we drive, placing celebrities in a lotus position on our hoods as they tell us about the miracle of whiter teeth, thicker hair, or smaller feet.
Obviously, these shocking interruptions will be unsettling. The advertisers will know this and the most popular products advertised in this fashion will be powerful stress-reduction drugs.
