Google's revenues rose 17% Y-o-Y in Q4 2009

"Google saw its revenues increase 17% between October and December, as its advertising earnings rose strongly.
However, its shares fell 5% in after-hours trading, as the results came in at the lower end of market targets.
The US search engine giant enjoyed revenues of $6.67bn (£4bn) during the quarter, up from $5.7bn a year earlier.
Its net profit also shot up to $1.97bn, but a comparison with a year earlier is difficult because of a one-off charge in the last three months of 2008."
