This article examines the reconfiguration of the global film industry in the streaming era through a comparative analysis of Nollywood, Hollywood, and Bollywood. It analyses how differences in industrial structure, production scale, capital intensity, labour organisation, revenue configuration, and global distribution strategies shape uneven growth trajectories. Particular attention is given to the role of digital streaming platforms in restructuring distribution, monetisation, and international market access. The study integrates political economy of communication, cultural globalisation theory, and creative industries scholarship to assess how platform dynamics intersect with local institutional contexts. Using qualitative comparative analysis of peer-reviewed scholarship, institutional reports, and recognised industry data, the article evaluates developments between 2015 and 2025 and offers scenario-based projections to 2035. The findings indicate that Hollywood retains economic dominance through capital concentration, intellectual property control, and diversified revenue streams, though growth is moderated by market maturity and rising costs. Bollywood maintains regional strength anchored in domestic and diasporic markets, yet faces linguistic fragmentation and saturation pressures. Nollywood demonstrates the strongest relative growth trajectory, driven by production volume, cost efficiency, and integration into global streaming platforms. The article contributes to comparative global film industry scholarship and clarifies how platformisation is reshaping hierarchies within an increasingly multipolar media economy.
