Networked Media Literacy era
Henry Jenkins, a central voice in the late 1990s and early 2000s, emphasized participatory culture and media convergence as drivers of how audiences produce, remix, and contest media within digital networks, shaping classroom and activist literacy practices. David Buckingham argued for critical media education that combines enjoyment with critique, focusing on how young people learn to read media texts, understand power, and participate responsibly in public discourse. Sonia Livingstone contributed empirical, cross-national insights into children's digital media use, access, safety, and empowerment, underscoring policy-relevant approaches to global media literacy. Manuel Castells provided a macro-level account of the network society, showing how networked infrastructures enable collective action and new public spheres, which grounded critical media literacy's activist potential in transnational contexts.
Platform and Infrastructure Governance era
In the Platform and Infrastructure Governance era (2005–2023), critical media studies treat platforms, algorithms, and network architectures as political actors that shape visibility, circulation, and the material conditions of collective action. Tarleton Gillespie's Custodians of the Internet analyzes how moderation regimes, design affordances, and governance rules embed power in platform logics that determine what publics can appear and be heard. Nick Couldry and Ulises Ali Mejias's data colonialism framework links digital infrastructures and data processes to political economy, sovereignty, and accountability, foregrounding how datafication reconfigures governance. Shoshana Zuboff's surveillance capitalism and Safiya Noble's work on algorithmic bias reveal how data-driven platforms reproduce inequalities through governance mechanisms, underscoring questions of accountability and civic resilience.
