PRIMEDIA's About Links With Google for Targeted Advertising: "As part of the deal, Google will become the exclusive provider of contextually targeted and search advertising across About.com, the Web's largest content site, and most of PRIMEDIA's Consumer Media and Magazines Group ('CMMG') websites. The deal extends the reach of Google's base of more than 150,000 advertisers to the targeted audiences served by About.com's 450 topic-specific Guide Sites that cover more than 10,000 topics and the CMMG 127 targeted magazine-related sites.
'Combined, the CMMG properties and About.com are among the largest providers of original content on the Internet today,' said Dean Nelson, Chairman of PRIMEDIA. 'Google's targeted advertising is a perfect match to our portfolio of high-quality content and large special interest audiences. Google's advertisers will benefit from this extended reach across a broad range of enthusiast-centric properties and on About.com's 450 Guide Sites and our users will benefit from relevant advertising.'"
