Microsoft's MSN Revenue Declined 3% Year Over Year

ClickZ reports that MSN's revenue declined 3 percent year-over-year. CFO Chris Liddell covers transition of search to Microsoft adCenter, saying "it's not far off that we're going to have 100 percent of our business on adCenter."

Microsoft plans on spending $500 million on adCenter, Windows Live, MSN Search and other online services this year. Next quarter results should be interesting.
