Global media convergence refers to the integration of communication technologies, cultural content, and digital platforms across borders, resulting in the hybridization of consumption habits, cultural identities, and socio-political narratives. This paper examines how converged media ecosystems—driven by streaming platforms, social media networks, gaming communities, and algorithmic content distribution—reshape cultural exchange, global perception, and soft power. A new analytical model, the Transnational Media Convergence Influence Framework (T-MCIF), is proposed to map four major influence vectors: Technological Integration, Platform Interoperability, Cultural Hybridization, and Political-Economic Governance. The study draws from cultural studies, communication theory, globalization research, and digital anthropology to explain how content flows produce new forms of cultural homogenization, resistance, and localization.
