Social movements have long been valuable components of the struggle for a world with true justice. Along with the changing and modernization of society these movements also change, both in their actions as well as in the goals they want to accomplish. Technology is taking a greater part in many aspects of social life, creating new dimensions but also new social divides. This thesis examines how new social movements make themselves visible and affect the world around them through different kinds of networks. For the purpose of this study, we have chosen to study two social movements; the Zapatistas in Mexico, who have become known worldwide for carrying out the first informational revolution, and MoveOn.org, an American grassroots organization that struggles for increased democracy in the US.
