Viral marketing

Viral marketing is a type of online marketing that aims to have a message passed from one person to the next under their own efforts to increase brand awareness. Viral marketing relies on self-replicating properties of a piece of engaging, unusual or funny advertising.

It began with email based content and after 2000 became synonymous with video clips and photographs. The arrival of social media in the mainstream of digital behaviour after 2004 created a series of new social networks for these messages to pass though.
