According to an article we found on PodcastingNews.com, podcasting audiences have grown 40% in one year. The article states that e-Marketer’s January 2008 Arbitron-Edison Media Research study found the following:

• The podcast audience has grown nearly 40% in the last year.
• Podcasting reaches 18% of the US population, up from 13% a year ago.
• Podcast adoption is accelerating. A year ago, they reported that the podcast audience had grown 18%, less than half of last year’s growth.
• An estimated 23 million Americans have listened to a podcast in the past month.

The key to growing these numbers is to continue to deliver great content. Content that either educates or entertains your audience. If you continue to work hard at delivering a great product, podcasting will continue to grow in the collective awareness and continue to help folks learn, laugh and take advantage of this great communication tool on their time, whenever and wherever they want!
