Justice Probe of Google/Yahoo Deal Now Formal: Report

The Justice Department has begun a formal probe of the proposed Google Yahoo search deal, the Washington Post reports. The companies put the deal on hold for voluntary Justice review. "But a formal investigation signals that the department may have found some cause for concern," the Post reports.

Investigators are planning to demand documents not only from Google and
Yahoo, but also from other large companies in the Internet and media industries, said the sources, who spoke on condition of anonymity because the investigation is ongoing.
