An interesting survey was performed recently by Jacobs Media of 25,000 respondents from over 75 Rock-formatted radio stations from all over the US and the results were quite interesting, especially in regard to podcasting. Some pretty interesting statistics.
From the Report:
Finally, podcasting is having an impact. One-fifth (22%) of those who own an iPod or portable MP3 player say they’ve downloaded/listened to a podcast. Of this group, nearly two-thirds (64%) subscribe to at least one podcast, and a majority listens to most or all podcasts that come their way.
