And now an ad from Fanta – but not for grownups – published 2008
The team has developed a mobile application for Fanta that is only audible to teenagers.
The application is based on the same technology used to deter teenagers from hanging around outside shops and bus shelters, the Mosquito Teen Repellent, developed by Howard Stapleton.
The Fanta Stealth Sound System, uses high-pitched frequencies, only audible to the under 20s. It includes wolf-whistles, warnings, pssts and sound tags for phrases like “cool”, “uncool”, and “let’s get out of here”.
Apparently they are going to release it to the wild virally, so I guess it will be available from all the places teenagers hang out.
