Recently, social movements worldwide have introduced innovations in their communication methods. The #spanishrevolution that started on 15 May 2011 shows this new-style communication in action. Amidst regional election campaigning, thousands of people, mainly young, took to the streets and occupied Spain’s main squares, becoming known as the Outraged (los Indignados) or 15M Movement. This article evaluates how the Outraged involved with the #acampadabcn, the camp in Barcelona’s central square, used online–offline tools to get information about the Movement. This research combines participant observation, surveys, in-depth interviews, and web analytics. The results show that social media were vital for getting information during 15M. While the majority of those surveyed became aware of the camps via word of mouth, a posteriori it was social media that were the main tools for informing and mobilizing. 15M Movement, together with networked social movements, has updated the communication methods of social movements.
