Today, Google reported its financial results for the fourth quarter of 2011, which ended December 31. The web giant reported $10.58 billion in revenue and $8.13 billion in net revenue, well below the $8.4 billion that was predicted by analysts. Despite missing expectations, Google's full-year revenue grew by 29% and this is the company's first quarter where revenues are above $10 billion. 

Google's operating expenses increased to 32%, compared to the 30% from the year-ago quarter. The amount of clicks on advertisements in Google searches increased in the last three months of the year, but the amount of money Google charges advertisers actually decreased by 8% from Q3 2011. Google reported a net income of $2.71 billion in the fourth quarter of 2011. 

Finally, Google CEO Larry Page confirmed that Google+ now has over 90 million users. 

Google's stock (trading under the symbol "GOOG") was up about 1% on the day, but is down nearly 9% in after-hours trading.
