Insight to IBOC, May 2010

Periodically, we have tracked the progress of the HD Radio rollout by state. Through 2008, the number of stations adding HD Radio saw a steady increase. From 2009 to today, the roll out has slowed slightly, but the numbers continue to increase. The 1,000 station mark was achieved in September 2006, and we are now almost at the 2,000 station mark.

According to the latest tallies from Ibiquity, every state has at least three stations transmitting an HD Radio signal now. California, Texas, Florida and New York have led in station counts all along. All states have added at least one HD Radio station in the past two years.
