These numbers are extremely close to the Edison numbers on podcasting and certainly validate that study’s conclusion that podcast consumption continues to grow. This is a good study, and a worthy addition to the growing body of credible research out there on the consumption of downloadable media.

The Pew report does draw one conclusion that is likely to draw comments from a number of podcasters, if not outright controversy. With 3% of Americans indicating that they download podcasts “on a typical day” (and 17% of actual podcast consumers claiming the same), the data suggests, as Mary Madden indicates, that “podcasting has yet to become a fixture in the everyday lives of internet users.” One could point to the “300% increase in the daily podcast audience” here, as the headline reads in today’s Podcasting News, and see the glass half full, or one could focus on the number “3″ and be fairly dismissive of podcasting.

The truth, as it generally is, lies in between, and is best summarized just exactly as Madden has written–podcasting has proliferated, but has yet to become a fixture in daily life. The overall consumption numbers from both the Pew and Edison studies (one in five Americans) show that podcasting is becoming important on a national scale–but it isn’t yet a “daily habit.” I think a lot of that has to do with the fact that podcasters don’t really “ask for the order,” a phenomenon I wrote about at length on this very site in an article entitled “Podcasting: The Curse of Convenience.” Because you can listen to a podcast any old time, there is not necessarily a daily urgency to do so. There aren’t many daily shows, for one thing–and I often wait until the end of the week to even sync my portable MP3 player. “Daily” may not even be a reasonable standard–radio is measured on weekly reach (Edison’s data puts podcasting’s weekly reach between 8 and 9 percent) and television is measured on the “show,” both of which are more reasonable standards for podcasting.

Still, the essential conclusion here is correct–podcasting continues to proliferate, but is not yet a daily habit, even for most podcast consumers. The key to reinforcing daily podcast consumption is to reinforce its relevance to the lifestyle and context of the listener–keep teaching your listeners how, when and where to listen to or watch your content.
