SAN FRANCISCO -- Google(GOOG Quote) fell short of Wall Street earnings estimates for the second quarter, sending the stock plummeting after hours.

"Strong international growth as well as sustained traffic increases on Google's web properties propelled us to another strong quarter, despite a more challenging economic environment," said Eric Schmidt, Google's chief executive. "As we continue to focus on innovating in our core business of search, ads and apps, we also look forward to enhancing the experience of our users and expanding the reach of our advertisers and partners with new technologies and formats, particularly as our integration of DoubleClick gains momentum and creates new opportunities in display advertising and elsewhere."
