Facebook creator Mark Zuckerberg unveiled a new ad-selling strategy today that will allow companies to create their own pages on the social networking site and zero in on customers based on their profiles. Users can sign up with advertisers they like and share information about them in their network. Advertisers also will get detailed information about the people who see their ads to hone their marketing.
"This is some really powerful stuff, and nothing like this has ever been seen before," said Zuckerberg, ignoring MySpace's announcement of a similar program yesterday. "Pushing your message out isn't enough anymore." Zuckerman said the program, called Facebook Ads, would not constitute an invasion of privacy for the site's 50 million users. "No direct personally identifiable information is ever shared back with marketers," he said. (More Facebook stories.)
