For my communications class, I needed to write a paper about the radio industry using information found in trade papers. To do this I had signed up with the website MediaPost.com. It was very helpful and provided me with a plethora of articles, including those relating to the radio industry as well as other forms of media.
One report I found there was the following: http://www.mediapost.com/publications/?fa=Articles.showArticle&art_aid=117009&lfe=1. It discusses radio's usage, which is what I decided to write my paper on.
I was somewhat surprised by the article's findings. It explained that despite the rise of iPods and other forms of audio media, radio is still the most popular. And rather than iPods and their mp3 ilk taking away from radio's strength, the article explained that those with such players were actually more likely to listen to the radio! Very insightful. I will discuss this further in another blog post.
