In spite of the growing visibility of international summits in the last decade, little is known about how these events actually unfold. Neither the role played by the media in these highly scrutinized gatherings, nor the organizational setting in which information is produced have been extensively described. Focusing on one such summit, this article shows what a close-up view of the otherwise invisible media center can offer to sociological analysis. Year after year, these spaces have increasingly been colonized by certain NGOs attempting to influence the proceedings of these summits. This article highlights some of the overlooked factors that make some groups better able to promote their cause. It lays bare the mechanisms of “mediated pressure,” by which NGOs try to influence negotiators through the dissemination of their claims in the news.
