Google Hits European Hurdle on DoubleClick Deal - New York Times

Perhaps the same European regulators to whom Google and others have complained about Microsoft concluded that Google already has an "inappropriately" large market share... 

The inquiry is one of the few major business challenges that Google, the dominant Internet search engine and a stock market favorite, has encountered in its nine years. The company makes most of its money from text advertisements that appear next to search results and on partner sites, while DoubleClick, a privately held company, places banner ads on Web sites and sells analyses of who sees them.

“We are obviously disappointed,” Eric E. Schmidt, chief executive of Google, said in a statement. Saying the company would work with the commission, he added, “We seek to avoid further delays that might put us at a disadvantage in competing fully against Microsoft, Yahoo, AOL and others whose acquisitions in the highly competitive online advertising market have already been approved.”
