Microsoft's fiscal year third quarter ad revenue at MSN trailed overall growth in online advertising, totaling $357 million, a 7 percent increase from 2005 - compared with 80 percent rise in ad revenue at Google and 36 percent at Yahoo, writes AdWeek. Microsoft blamed the results on its current migration from Yahoo-provided search ads to those from MSN's adCenter.

Overall revenue at MSN, including online advertising and MSN internet service subscriber fees, was $561 million, down 3 percent from the year-earlier period. MSN posted a $13 million loss, compared with net income of $102 million a year ago.

Microsoft said it plans to increase capital spending in various areas, including MSN and the Xbox, to $2.4 billion.
