Keeping Score: 1Q08 Online Ad Growth

Microsoft/MSN showed solid online advertising growth, growing 39% in Q1 worldwide to $619 million. If you subtract aQuantive's ad revenue of $47 million, it still grew 29%. MSN, however, suffered over $200 million in losses.

So, if you're keeping score, and my calculations are correct, worldwide online ad sales growth for Q1 is looking like this:

Google (ex-TAC)                              $3.75 billion, up 45%
Yahoo (ex-TAC)                               $1.1 billion, up 13%
Microsoft (minimal TAC included)    $619 million, up 39%

AOL still to come.
