This pioneering work examines the history of early radio broadcasting in the Philippines during the colonial period (1922–1946). Through archival research, interviews with period broadcasters, and analysis of extant publications and memorabilia, Enriquez traces how early Philippine radio was shaped by colonial influences and how local society appropriated and adapted this medium. As one of the only extensive scholarly works on Philippine broadcast history, the book provides crucial insights into the development of mass communication in the island nation during this formative era.
