Empires' Echo: Media and Communication Technologies in Puerto Rico tells the story of Puerto Rico through the systems that have connected, controlled, and shaped it for centuries. From carved wooden saints and oral traditions to newspapers, radio, television, and digital platforms, the book traces how communication has organized everyday life on the island. It shows how Spanish and U.S. empires used media and infrastructure--roads, telegraphs, broadcasting networks--not only to connect territories but to exercise power. At the same time, Puerto Ricans adapted these systems in creative ways, using them to build culture, express identity, and challenge authority. Spanning five centuries, the book reveals that communication is more than technology: it is the way people move, share ideas, and make meaning. By placing Puerto Rico at the center of global and Caribbean networks, Empires' Echo offers a compelling new perspective on how media shapes history, culture, and power.
