Media activism is activism that uses media and communication technologies for social movement, and/or tries to change policies relating to media and communication (media policy activism).
It includes publishing news on web sites, creating video and audio investigations, spreading information about protests, and organizing campaigns relating to media and communications policy. Attempts by grassroots activists and anarchists to use alternative media to spread information not available by mainstream news are also called media activism, as are certain forms of politically motivated hacking and net-based campaigns.
