On my commute, until recently, I've always listened to the radio, or played some tapes or CDs. Now I find I almost never listen to the radio, Pacifica and NPR are things of the past. I've been listening to material on my MP3 player. I listen to the podcasts "This Week in Tech" (lots of hot air but fun), "Inside the Internet" and other MP3 downloads. IT Conversations and Educause have lots of good items. Then there are the workshops like the Duke Podcasting Symposium. When I feel like music I have over 2000 tunes on the player.If this behavior is common and continues what does this mean for traditional broadcasting?
