Unilever, Red Bull, Mondelez, Samsung, BMW, Procter & Gamble and Volkswagen are among the advertisers that have signed up to join Facebook's new EMEA "client council." Facebook has published details of the council and its rationale on a blog post. It will help Facebook align its business priorities with the marketing needs of brands -- for instance, by fostering greater levels of creativity in copy and imagery used in campaigns on the social network.
