Digital activism refers to online participation in cause-related movements. In such campaigns, digital activists leverage networked technologies — YouTube, Twitter, Facebook, blogs, SMS text messaging — for social and political change campaigns.

As grassroots organizers take advantage of their digital tool belts, it is revolutionizing how activists rally. Via digital means, socially aware people can connect, and create change in a space that is free and global — the World Wide Web. In addition, individuals can organize large scale events, to create awareness and engage others for their cause, at virtually no cost.
