A story in the Wall Street Journal found that code inserted in display ads, including some placed by Google-owned DoubleClick, appears to have bypassed privacy settings designed to allow users of the Macintosh-based Safari browser to avoid the placement of third-party cookies. One Web developer familiar with the technique said that it was created to "ensure a consistent experience" for Web content and advertising viewed across multiple browsers. Google released a statement saying, "The Journal mischaracterizes what happened and why. We used known Safari functionality to provide features that signed-in Google users had enabled. It's important to stress that these advertising cookies do not collect personal information."
