On Tuesday, Yahoo! managed to completely reverse the losses that it had incurred last year, and went ahead to post its best quarterly earnings since Carol Bartz started heading the company as the Chief Executive.

The Sunnyvale, California-based Internet firm posted fourth-quarter net earnings of $153 Million, a substantial improvement when compared to the loss of $303 Million which was posted for the previous year's fourth-quarter.

Revenue, however, continued to fall, recording a 4% decline over 2009's last quarter, to $1.732 Billion.

Despite the fact that it was lower when compared to 2008's figure, the revenue did manage to beat the expectation pegged by Wall Street analysts, who were expecting revenue of $1.23 Billion, on per adjusted per share profit of 11 cents, which was actually 15 cents, again beating expectations.

"The fourth quarter marked a strong finish to 2009, which was a transformative year for Yahoo!. Our business has positive momentum and we feel good as we head into
2010", said a very delighted Chief Bartz.
