Abstract
This article focuses on analysing the phenomenon of the corporate blogs which have recently come up in France; it intends to understand the role(s) they play within the global communication strategy. The balance between expected benefices and potential risks is random as this tool, diverted from its original use, obeys to informal rules which are not yet clearly established. Moreover, this article defines the characteristics of those blogs in order to measure their pertinence and cogency for the companies. However, concrete illustrations demonstrate that an in-depth knowledge of the blogs does not always guarantee its success. It is then essential to wonder whether companies should create and develop a corporate blog or not?
