IDG’s Computerworld is Number One in Readership for Sixth Straight Year

FRAMINGHAM, MA – JUNE 13, 2006 – Computerworld today announced that it has once again been shown by IntelliQuest to be the most-read enterprise IT publication, reaching 1,337,000 readers every issue, 385,000 more readers than InformationWeek and 734,000 more readers than eWeek. This is the sixth year in a row that IntelliQuest showed Computerworld to be number one in readership in the category.

"As the only apples-to-apples measurement of IT publication readership, IntelliQuest continues to be the best way to compare our readership with that of other publications in our category," said CEO Matt Sweeney. "We're thrilled that year-after-year this study shows that the Computerworld brand is the most trusted, and relied-upon brand in the IT industry."

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 CIMS studies, that Computerworld outshines other publications in the category in terms of reaching readers who read deeper into each issue (75% or more), readers who read more of the issues they receive (3 or 4 out of 4 issues received) and read ads very or extremely closely:

-0- *T — Readers who read 75% or more of the publication: Computerworld: 543,000 InformationWeek: 322,000 eWeek: 223,000

— Readers 3 or 4 out of 4 issues of the publication: Computerworld: 600,000 InformationWeek: 501,000 eWeek: 401,000

— Readers who read ads very or extremely closely: Computerworld: 505,000 InformationWeek: 315,000 eWeek: 217,000

The CIMS study also confirmed Computerworld's place once again 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+ employee):

– Computerworld: 339,000

– InformationWeek: 322,000

– eWeek: 182,000

Sweeney went on to say, "As is the case every year with CIMS we'll now see every publication somehow spinning the results of this study in their favor. The bottom line is that for every subscriber that an advertiser pays to reach in Computerworld, they are reaching an additional six influencers at no additional investment. No other publication in the category comes close."
