Viral marketing

Definition: Viral marketing is a form of promotion where the topic spreads like a virus, hence its name. Popularized by the advent of the internet and social media, it involves using word of mouth (or “WOM” for word of mouth in English) to spread a message and promote a product or brand. The consumer is both the recipient of the offer and its medium. Generally speaking, viral marketing consists of optimizing the classic effects of word of mouth through the internet, in particular by encouraging internet users to forward a message to their contacts.
