TechCrunch reports that the Google DoubleClick deal is delayed another 4 months - Google-DoubleClick Deal Delayed in Europe 

"….Google’s big move into display advertising is going to be delayed, maybe until April, if it gets approved at all. The European Commission is holding up Google’s acquisition of DoubleClick on antitrust concerns, fearing that Google’s current dominance of search advertising, combined with DoubleClick’s leading position in display advertising will create an unstoppable force. "

"…This must be the only time Steve Balmer is tickled that Google is being treated like the new Microsoft). There are also related privacy concerns, as tracking consumers across sites with ad cookies becomes the industry norm, but that is beyond the official purview of the European Commission."

However, Techcrunch feels "….In all likelihood, the deal will go through with the European Commission demanding a set of tough, but ultimately misguided, concessions. "

Be interesting to see what happens in 4 months - or whenever the investigation is concluded.
