Turbo...That example is not subliminal.
Subliminal advertising first occurred at the movies.
Frames of film were replaced with parched desert scenes, thirsty people, hunger scenes...and then near intermission, they showed individual frames of refreshments, popcorn and candy......and fresh faced satisfied young women.
Sales at the counter went through the roof. It was phenomenal......and outlawed shortly thereafter.
Penalties were quite large as only the subconscious is capable of recognizing and...evidently processing the data.
Yet...inspectors looked at each frame of film. Supposedly the practice died.
(Who can believe that?)
Later in the 60's....Playboy magazine was heavily involved in subliminal advertising in .....ice of all things depicted in whiskey.
There were others of course...anybody remember the famous Playboy Christmas Wreath?
The ice in a glass was really art....and scenes depicting sex, group sex and various sexual parts of the female anatomy were depicted........but to the casual observer....it was a glass, ice and whiskey.
It would not surprise me a bit to find subliminal advertising on the net. Done right no one notices. We could be receiving subliminal messages right now!!!!
That sure would explain liberalism!
