Struble presented two key distribution indicators:
- Car adoption: 16.5-million equipped cars on the road
- Station adoption: 2,200 U.S. radio stations are transmitting in HD digital.
For additional color: Every “major” car company installs HD receivers in at least some of its models, and a new HD-equipped car is sold every four seconds. Those 2,200 radio stations represent 78% of U.S. listening, and 94 of the top 100 stations, in terms of billings, use HD.
