"This MRI data shows that no other computer or business magazine can match PC World in total audience," said Jeff Edman, publisher of PC World. "As a consequence, PC World offers a winning combination for marketers: targeted reach to active direct and Internet buyers. Busy managers are turning to the direct channel — especially online — to purchase computer products, and PC World’s award-winning editorial is the most effective in attracting these decision-makers. Also, MRI’s qualitative data shows that business computer product buyers spend more time reading PC World, and average page exposure is higher, than PC Magazine. This is good news for advertisers who count on print advertising to drive sales, online and off."
