Google released its forth quarter results Tuesday, posting revenues of $1.919 billion for the three month period ending December 31, 2005.

"We are very pleased with our results for the fourth quarter as we achieved excellent performance across our businesses," said Eric Schmidt, CEO of Google in a press release issued late Tuesday. "We generated significant revenue growth in our core search and advertising business, driven by continued strength in traffic and monetization. We will continue to invest significantly as we develop innovative new products and as we extend our core technologies to new user access points and to different channels."

Unfortunately for Google stock holders, record profits built on an increasingly diversified stable of products and services simply wasn't enough to please Wall St. analysts who had expected larger returns. Google's share prices dropped below $400 in the largest drop in value since their initial public offering in August 2004. (Google shares closed slightly higher at $401.78 by the end of the day at NASDAQ.)
