From the link:

During Microsoft’s fiscal third quarter, which ended March 31, the Online Services Division, or OSD, reported a 12 percent increase in revenue, which rose to US$566 million on the back of higher advertising revenue. That wasn’t enough to offset a surge in operating expenses during the period. The division’s quarterly loss grew by 73 percent to $713 million, compared to a loss of $411 million during the same period last year.

OSD includes Microsoft’s online advertising business, the Bing search engine, and its various MSN websites.
