Free Analysis of Individual Podcast Audiences Offered to Advertisers and Podcasters through Podtrac.com

PORTABLE MEDIA EXPO AND PODCASTING CONFERENCE, ONTARIO, CA -- November 11, 2005

Podtrac, which offers a new advertising service for the podcasting market, has joined forces with Mediamark Research Inc. (MRI), the country's leading provider of magazine audience and multimedia research data for publishers, agencies and advertisers, in order to bring the same demographic research that advertisers have in traditional media to podcast media. Through this relationship, Podtrac can help advertisers make confident and targeted decisions in their podcast media buys.

MRI and Podtrac will provide ratings data, including an index of the data to MRI's Survey of the American Consumer as a free service to any podcast through Podtrac. The Survey of the American Consumer is a national probability study of U.S. adult's demographics, media and product usage, attitudes and lifestyle. Podcasters will start by implementing Podtrac's free Podcast Audience Survey. Podtrac will calculate indices to the Survey of the American Consumer for individual podcast survey results and provide the data to advertisers and podcasters free-of-charge. The Podtrac Audience Survey with an index to MRI is the first of its kind to enable advertisers to understand podcast listening audiences.

"The Podtrac Survey together with an index to the Survey of the American Consumer provide a powerful tool for advertisers to determine the fit of a specific podcast audience for the target of their advertising," said Mark McCrery, CEO of Podtrac. "The demographic indexing service also provides podcasters with an unprecedented way of turning their podcasting listening or viewing audiences into a compelling marketable asset to advertisers through Podtrac."

"We see the podcasting market as an interesting and potentially powerful new advertising medium," said Paul Gold, Vice President of Interactive Research at MRI. "We have come together with Podtrac to make it easy for advertisers to analyze, compare and contrast media buys by working with the same indexing research they use for other media."
