Through a unique two phase summit, the World Summit on Information Society (WSIS) created an agenda for the information society in 2005. In 2015, the UN General Assembly reconvened to review the outcomes of the WSIS process and to address the new challenges facing the information society over the last decade. This report outlines the civil society actors involved in the Review process, the methods they used, their priorities and the overall impact they had by drawing upon on a survey of civil society actors who had participated in the review process, as well as extensive analysis of all written submissions to the Review. While the scope of the paper is not large enough to prove direct causal links between civil society actions and the outcomes of the Review, its findings provide a vibrant snapshot from which we can make inferences on the nature of the process, its power dynamics and the role of civil society going forward.
