Buzz marketing is a set of marketing practices aimed at using buzz phenomenons to promote a product or service launch or to amplify a marketing or advertising campaign.
At first the buzz term has been used to refer to the echo given to a product or service before its launch. After a semantic shift, buzz marketing is now seen as a synonym of viral marketing or word of mouth marketing (WOMM).
Buzz marketing should not be confused with a simple buzz phenomenom as buzz marketing implies marketing planification and budget.
A bad buzz is a buzz phenomenon but not a buzz marketing action allthough it has marketing consequences.
