Social movements aim to work toward a common social goal of creating change. They can occur at local, state, national, and global levels. Sociologists identify different types of social movements based on the level of change sought, from reform to revolutionary. Social movements also typically progress through stages from preliminary awareness to institutionalization or decline. Recent technological advances have transformed how social movements organize through social media, allowing rapid awareness and organizing across large networks. However, critics argue social media only increases superficial participation rather than deeper engagement. Theories seek to explain success of social movements through concepts like resource mobilization, framing of issues, and alignment of different movement goals.
