Microsoft's online services division, which includes Bing, lost $728 million in the second quarter -- and $2.6 billion over the past 12 months, according

Yet, as Cyran notes, "The company thinks search makes Microsoft's offerings in everything from mobile phones to business software more compelling," to which he adds, "Perhaps, but there's little evidence [of that] to date."
