*Analysis by PC World

Paid circulation is the truest indicator of a magazine's strength because paid subscriptions and newsstand sales show that readers are proactively spending their money for a specific publication, as opposed to analyzed, non-paid circulation where a reader receives issues for free. Despite a higher cover price, PC World outsold PC Magazine by over 71,000 and Computer Shopper by over 46,000 in single copy sales for the last half of 2003, demonstrating that readers are willing to pay a premium for PC World's award-winning editorial. And its paid subscription level is unmatched.

"Based on the December 2003 ABC Publisher's Statements, PC World surpassed PC Magazine's total paid circulation by nearly 187,000 copies, or 20%, and Computer Shopper's by over 600,000 copies, or 120%," said Bob Ostrow, Publisher of PC World. "Our dominant position in both newsstand sales and paid subscriptions reflects the popularity of our publication among readers."

According to Shawne Burke Pecar, Vice President of Consumer Marketing for PC World, press information released by Ziff Davis, publisher of PC Magazine, indicates Synapse is a major source of analyzed, non-paid circulation for PC Magazine. Pecar added: "After a review of the magazine's 2003 Audit Report, multiple sources of analyzed, non-paid circulation were identified including transferred subscriptions from discontinued publications and market coverage copies. We're pleased to assure our advertisers that no Synapse Freebizmag.com-generated subscriptions are on our subscription file nor are there transfers from defunct publications."

PC World President & CEO Jeff Edman noted: "Advertisers make media decisions based on value and the most basic media yardstick in determining this is net paid circulation. The gold standard of measuring that is ABC and, while it's disturbing to see a competitor missing its paid circulation rate base by such a wide margin, we're proud that PC World has provided full value to its advertisers."
