Quick Summary
HD Radio, or hybrid digital radio, is a technology that allows broadcasters to transmit more channels and offer clearer reception than traditional analog radio. Despite its name, HD Radio is not high-definition in the same way as high-definition television. It requires new tuners for listeners to access its features. While it promised improvements, it offered little in the way of new programming and ultimately struggled to gain widespread adoption as listeners moved to other media like internet radio and streaming services.12
