According to new forecasts from The Diffusion Group, a consumer technology research consultancy, demand for time-shifted digital audio files or "podcasts" is expected to grow from less than 15% of portable digital music player owners in 2004 to 75% by 2010. TDG's new report, Podcasting: Fact, Fiction and Opportunity, suggests that between 2004 and 2010, the use of podcasting among US consumers will enjoy a compound annual growth rate of 101%. These claims are reflected by recent commercial podcasting activity. ABC and NBC (along with MSNBC and CNBC) are using podcasting to offer recorded newscasts via online downloads. National Public Radio, Infinity Broadcasting, and even Clear Channel Radio have teed up a number of popular radio programs for podcasting. Even Business Week created a special audio blog to accompany its recent analysis of the podcasting phenomenon.
