Have you ever heard of the term “Viral Marketing" heard? I've read about it many times - but I haven't found a really good definition yet. Until now! Under the adress www.connectedmarketing.de I found a very good explanation:
“Viral marketing is the targeted attempt to place an offer on the market in such a way that it spread by itself in the population, i.e. as intensively as possible in its user acquisition word of mouth effects benefits. By the way, trying to spread viral commercials is not the same. Because, as mentioned above, the supply must spread itself. In the case of viral films, however, it is not the advertised web platform that spreads, only the film. And whether that will bring new users is mostly in the stars.
Anyone who produces advertising anyway, for example for physical products, can work with viral films. These cannot spread themselves on the web. So advertising has to do it, or word of mouth about the respective product. But if I have a digital product - which means it's perfectly capable of spreading on the web - then I shouldn't waste time making funny little films, but instead focus all my energies on making my product infect its users on the web."
A not so good explanation, but a funny discussion on the subject "Viral Marketing” provides the following YouTube film:
