Increasingly, technology products are used for home and leisure activities as well as for business applications making it critical for advertisers to reach individuals who incorporate these products into all aspects of their lives. This highly-desirable group, Tech-Savvy Managers who buy, use, and integrate technology at work, home, and everywhere in between, has long comprised PC World's core audience. As demonstrated by IntelliQuest CIMS, Fall 2006, PC World is the most effective way to reach these consumers of technology for business and home.

"We're pleased that once again this respected study has confirmed that PC World's award-winning editorial has attracted the most technology purchase influencers within its competitive set," said Jeff Edman, president and CEO of PC World Communications, Inc. "But equally important to advertisers is the intensity of their readership since this increases the likelihood of their ad being read and acted upon."
