William Diaz was quoted in an October 31, 2007 article published by Competition Law360 regarding Google Inc.'s $3 billion takeover of DoubleClick Inc., an internet advertising firm. As a partner in McDermott's Antitrust and Competition Practice Group, Mr. Diaz stated that the Australian Competition and Consumer Commission's decision to approve the merger would be taken into consideration by the European Union and the United States, but that E.U. and U.S. regulators would likely face opposition to the merger. "It's certainly a positive step, but I would say that it's still too early to tell. At the end of the day, it still depends on what's happening in their own domestic boundaries," he said. "If they have competitors complaining or customers complaining, it will still be an issue and Google will have to start all over again," he added.
