There have been digital radio broadcasts in the USA for quite some time, but unlike television the FCC has not set a date to end analog radio broadcasting. The "legacy" problem is even larger than it was for TV, with no easy way to adapt any old radio to digital. Adoption rate of digital radio has been very slow. If the FCC had a mandate for every receiver manufactured after a certain date be required to have a digital tuner, the radio stations would have been upgrading to digital. Then once enough of a majority of actively used receivers had digital capability, analog broadcasts could be shut down - making all those old analog radios into paperweights and doorstops. One digital radio thing that has been added to many newer receivers, especially for automotive use, is Radio Data Service that can send information like song titles or road construction info and emergency warnings. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
