Viral marketing has become a mainstream concept. Yet most articles and videos I encounter on a daily basis do not explain it in basic terms. The following video I have attached below provides a simple and to the point demonstration of what is viral marketing and how it uses consumer advocates to spread the WOM (word of mouth) of a product among consumers. I found it on youtube and it was done by VM-People a viral marketing firm based in Germany.
