Some developments related to Google Inc.'s new privacy initiative:
Wednesday: Rival Microsoft Corp. runs full-page newspaper ads slamming Google and its new policy. Microsoft uses the opportunity to tout its own Web-based alternatives, saying for instance that users of its free email service, Hotmail, don't have to worry about the content of their emails being used to help target ads.
Friday: The European Union's data protection authorities release a letter to Google asking the company to delay the new policy until they have verified that it doesn't break the bloc's data protection laws. Google says it had briefed data protection agencies beforehand and had heard no substantial concerns then.
