HD radio was a very failed attempt to combat technology, and how that technology is hurting terrestrial radio. For many years, the HD Radio "Superpac", the people buying radio airtime to promote HD, was the biggest advertiser in the radio industry! The biggest advertiser!!! Even RADIO PEOPLE don't know what HD radio is and how it works, how is a consumer suppose to know. Plus, the cunsumer DOES NOT CARE. The really don't care with anything to do with radio. IF this were an APPLE rollout of a thing called HD, do you thing it would create some interest?? OF course it would, because people are interested in APPLE - they have lost interest in radio, and it is the industrys fault. Radio, with the exeption of talk and complete local content, is losing and will lose the war, and it won't be long. The HD thing was a great example of how radio has ZERO pull with consumers anymore. I have NO idea where Arbitron gets it numbers that says soooo many people are listening to radio, but they have to be wrong. I wish they would include, IPOD in those surveys, Pandora, XM, IHEART, SPOTIFY, etc.
