IDG’s Computerworld is No. 1 in Readership for Fifth Straight Year; IntelliQuest CIMS 2005 Finds Computerworld Has Best Reach and Most-Loyal Readers

FRAMINGHAM, MA – OCTOBER 11, 2005 – Computerworld today announced that it has once again been shown by IntelliQuest to be the most-read enterprise IT publication, reaching 355,000 more readers each issue than InformationWeek and 748,000 more readers each issue than eWeek. This is the fifth year in a row that IntelliQuest has shown Computerworld to be No. 1 in readership in the category.

The IntelliQuest CIMS 2005 Business Study, the only independent apples-to-apples measurement of IT publication readership, also showed that both InformationWeek and eWeek saw their readership drop year over year (by 9.1% and 21.7%, respectively), while Computerworld's readership increased by 13.6%.

"Coming off of Computerworld's best year in a decade, it's great to get affirmation that we're still No. 1 in the minds of IT influencers," said President, Publisher and CEO Matt Sweeney. "Our audience-focused editorial approach has led to our industry-leading reach not only in print, but also online and at our high-touch, face-to-face events."

The CIMS study showed that in addition to reaching more business influencers than any other enterprise IT publication, Computerworld continues to reach the most-loyal readers. IntelliQuest showed, as it has in the past four CIMS studies, that Computerworld is No. 1 at reaching readers who read deeper into each issue and who read ads very or extremely closely:

— Readers who read 75% or more of the publication:

Computerworld: 550,000

InformationWeek: 316,000

eWeek: 198,000

— Readers who read ads very or extremely closely:

Computerworld: 499,000

InformationWeek: 286,000

eWeek: 188,000

The CIMS study also confirmed Computerworld's place at the top in terms of reaching its core target of IT management in midsize to large organizations.

— IT management at midsize to large organizations (100+ employees):

Computerworld: 336,000

InformationWeek: 312,000

eWeek: 193,000

Sweeney went on to say, "In the coming months, IT marketers will be bombarded with messages from different publications, spinning the results of the study to highlight their strengths. No matter how you slice the results, the simple truth is that Computerworld reaches the most influencers and the most tuned-in influencers in the industry."
