This document summarizes the challenges facing radio as it transitions to digital transmission and distribution. It outlines two facets of digitalization: 1) transmission digitalization using standards like DAB and HD Radio, and 2) adapting to new distribution platforms on the internet. The document argues that in the US, HD Radio was pushed as the standard due to market capture rather than robust technological evaluation. Adoption of HD Radio has been low, with few listeners and declining awareness. It suggests radio must embrace new online distribution methods to engage younger listeners and avoid becoming outdated. The future of radio transmission standards remains uncertain and in need of reevaluation.
