The press release goes on to explain that "according to the 2005 IntelliQuest CIMS Business Influencer Study, the combined reach of CIO, Computerworld, InfoWorld, Network World and PC World is nearly four million technology business influencers. IDG reaches over two million more business influencers than CMP Media and nearly one million more than Ziff Davis."
It continues saying "The IntelliQuest study shows that corporate IT professionals are the most important influencers in the purchase of technology and that IDG is the undisputed leader in reaching these individuals. IDG reaches 44 percent more IT influencers than CMP Media and 48 percent more IT influencers than Ziff Davis."
Why is this interesting you may ask? Well, it does look like this conveniently timed press release is shouting "Look at us; we are worth buying too!".
Ok, so the press release explicitly compares IDG publications with other established media, not with weblogs. They also target the IT Influencers, according to the release the ones with authority to spend more than $500,000. This is hardly the same target segment of more consumer oriented blogs, but it seems that enterprise is reading weblogs more and more, so their target readership may overlap here.
