PRIMEDIA CHOOSES E-BOOK SYSTEM’S DIGITAL FLIP® TECHNOLOGY FOR SELECTED ONLINE PUBLICATIONS

(SANTA CLARA, CA — May 11, 2004) PRIMEDIA, the leading targeted media company, will use E-Book System’s Digital Flip® Technology for the online versions of Import Tuner. E-Book Systems—the leader in 3-D Digital Flip® technology—creates dynamic 3-D page-turning digital “FlipBooks” out of any document.

Published by PRIMEDIA, Import Tuner is the fastest growing magazine in the import market, reaching the youngest and most lifestyle oriented automotive enthusiasts. Import Tuner covers more than just the industry; it also covers fashion, music and entertainment trends. In addition, product testing, hands-on installation techniques and race coverage complete this ultimate, automotive performance magazine.

Now, with the Digital Flip® technology, visitors who go to www.importtuner.com can simply click on a link to automatically download the magazine and install FlipViewer™, which allows visitors to view the magazine as it appears in the printed version. Once the program is downloaded and for all subsequent visits, the reader needs only to click on the magazine link on the site and the FlipBook version of the publication will open immediately.

“The eBook functionality creates a user experience that is as close to reading a physical magazine as we have seen yet,” says John Stewart, Vice President and Group Publisher for PRIMEDIA’s International Automotive Magazine Group. “This is the type of offering our readers will relate to and embrace, and is an example of the forward-thinking position that our readership has come to expect. We feel strongly that the success of this product will lead to a larger rollout across our other titles over time.”

Import Tuner will also use another one of E-Book’s products, FlipAnalyzer, which tracks the usage of FlipBooks in terms of page views, click throughs, and time spent on reading content pages and ads and will generate reports to help the publisher manage the effectiveness of their FlipBooks content distribution strategy.

“We are excited that PRIMEDIA will be using our technology for Import Tuner and we hope to see more magazines using this innovative technology to create more eMags, which will help publishers reduce printing and distribution cost. The realistic book-like interface provided by our DigitalFlip® technology will provide readers with a superior on-screen magazine reading experience that makes it a perfect substitute for the paper version,” stated Seng-Beng Ho of E-Book Systems.

PRIMEDIA is currently offering a special rate to charter subscribers to the digital version of Import Tuner. An annual subscription to the digital version of Import Tuner is priced at $14.97, representing a 50% discount from a traditional print subscription. Single digital copies have a price of $2.97.
