Our media systems are in crisis. Run by unaccountable corporations and dominated by agendas and algorithms that are shrouded in mystery, these formerly trusted sources of information and entertainment have lost their way. As consumers, we have plenty of choice, but as citizens we have an abundance of misinformation and misrepresentation. In this incisive manifesto, four prominent media scholars and activists put forth a roadmap for radical reform of concentrated media power. They argue that we should put media justice, economic democracy and social equality at the heart of our scholarship and our campaigning. The Media Manifesto delivers a sharp analysis of our communications crisis and a passionate call for urgent change. It provides resources of hope for media reform movements across the globe.
