Online Advertising, First Quarter Earnings | featured news

Microsoft said Thursday that an accounting adjustment to reflect a weak online ad business led to its first quarterly loss in its 26 years as a public company. The software company had warned that it was taking a $6.2 billion charge because its 2007 purchase of online ad service aQuantive hasn't yielded the returns envisioned by management. The non-cash adjustment is something companies do when the value of their assets decline. Microsoft Corp. paid $6.3 billion for aQuantive, only to see rival Google Inc. expand its share of the online ad market.

An advertising industry group says revenue from Internet advertising in the U.S. hit $8.4 billion in the first three months of the year. That's the highest for the first quarter, up 15 percent from $7.3 billion in the same period last year.

Shares of online marketing services provider ValueClick are taking a beating after hours Wednesday following the company's Q1 financial report. ValueClick posted revenue of $152.9 million, up 31% from a year ago, but below the Street consensus at $157.8 million. Guidance had been for $155 million to $160 million.
