A new report from Pew Internet & American Life Project on podcasting:

Some 12% of internet users say they have downloaded a podcast so they can listen to it or view it at a later time. However, few internet users are downloading podcasts with great frequency; just 1% report downloading a podcast on a typical day.
Hmmmm… I download a few podcasts and burn CDs for my drives back and forth to Illinois. My use has increased this year as I find the podcasts that engage me. Look at the PDF of the report to see the small upswing of use through 2006. I wonder what these numbers will look like in a year.
