"Our ongoing innovation in search, ads, and apps helped drive healthy growth globally across our product lines, yielding another strong quarter for Google," said Eric Schmidt, CEO of Google. "As we integrate DoubleClick into our advertising platform, we see exciting new ways to improve the user experience and increase value for our advertisers and partners. Also, while exercising operational discipline, we continue to explore opportunities that add value to users everywhere and to Google in the long term."
Google's results for the quarter ended March 31, 2008, include the operations of DoubleClick Inc. from the date of acquisition, March 11, 2008, through the end of the quarter, and are compared to pre-acquisition results of prior periods. The overall impact of DoubleClick in the first quarter of 2008 was immaterial to revenue and only slightly dilutive to both GAAP and non-GAAP operating income, net income and earnings per share.
Google reports its revenues, consistent with GAAP, on a gross basis without deducting traffic acquisition costs, or TAC. In the first quarter of 2008, TAC totaled $1.49 billion, or 29 pc of advertising revenues.
