The HD Radio rollout is still experiencing momentum, according to iBiquity Digital.
As the installed base of HD Radio receivers rapidly increases, so has listening to HD2/HD3/HD4 programming. According to the latest Spring 2013 Arbitron Radio Nationwide audience estimates, more than 4 million people listen to an HD2, HD3 or HD4 channel in an average week.
This represents a 238% increase in Average Quarter Hour audience from the Fall 2011 survey. During the same period, Cume audience grew at over 200%.
HD Radio receiver sales are approaching 15 million. More than 12 million of those are in new cars or are auto aftermarket units.
About 30% of all new cars sold this year include HD Radio technology. Company President/CEO Bob Struble predicts that figure will rise to half of all new cars next year.
