Forgive DoubleClick CEO David Rosenblatt. As his company's merger with Google drags on, he must not have gotten a chance to attend new-Googler orientation yet. Some day he'll learn to toe the company line. Google has forbidden employees to speak on the Microsoft-Yahoo deal, but today AlleyInsider caught Rosenblatt telling the crowd at the DeSilva+Phillips conference in New York that the Microsoft-Yahoo merger makes sense. At least for Microsoft.

Does this make sense relative to their other options? I think it does. Their current strategy is less likely to work without Yahoo. With Yahoo, they are guaranteed a seat at the table for a long time. Even if integration is bloody and long, it will still leave them in a better position. Their market share will be extroardinarily high. They will control 50 percent of the display ad business out of the gate. They will be dominant.
