The PEW Internet & American Life Project has conducted surveys over the past couple of years regarding America's downloading habits as they pertain to Podcasts. In a report published in August of this year the group has found that Internet users who have ever downloaded a podcast went from 7% in February of '06 to 19% in May of this year. Users who download podcasts on a daily basis went from 1% to 3% over the same time period. Check out the pdf version of the report here.
