International Data Group Publications Extend their Reach to Technology Buyers and Influencers

BOSTON, MA – OCTOBER 22, 2003 – International Data Group (IDG) – the world's leading technology media company–scored impressive gains in the recently released Millward Brown IntelliQuest CIMS v.10.0 business influencer study. The combined, unduplicated reach of the IDG publications–CIO Magazine, Computerworld, InfoWorld, Macworld, Network World, and PC World–is more than eight million US business technology influencers, an increase of nearly 500,000 from last year's survey1. IDG leads its US competitors, Ziff Davis (4.6 million)2 and CMP (2.7 million)3, in total reach in the IntelliQuest CIMS v10 study.

IDG also leads Ziff Davis and CMP in reach to corporate IT professionals, the most powerful group of buyers of technology products and services. Nearly 1.4 million corporate IT influencers read one or more IDG publications4. With its IT enterprise media, IDG produces publications that are read by the largest number of senior IT executives5, as well as those with the largest technology budgets: professionals spending more than $500,000 a year on products and services6.

"The survey results are very impressive given the difficult economy," said Pat Kenealy, CEO of IDG. "The research shows that technology decision makers continue to rely on us to make buying decisions both for the office and home." Kenealy continued: "All six IDG publications grew their readership this year compared with 2002 and that's a testament to award-winning editorial coverage."
