Podcasting News first alerted me to a new study by Bridge Ratings about the effect of MP3 or digital audio players on traditional radio listening. As Podcasting News points out the portable digital devices have a real impact on the younger demographic but the report concludes overall, “This first look at a three-month composite of radio users suggests an increase in time spent with traditional radio the longer radio listeners own these digital players.”

You can look at the full report here. Bridge Ratings is “dedicated to providing on-going, immediate, reliable and affordable audience measurement services for radio.”
