Yahoo's 2011 revenue dips 21 percent

Yahoo has reported a decrease of 21 percent in its revenue for the year ended December 2011, from the same period of 2010.

The revenue of the company stood at $4.98 billion, compared to $3.94 billion in the year ended December 2010. The company says that the dip is primarily due to the required change in revenue presentation, related to the search agreement and the associated revenue share with Microsoft.

The fourth quarter revenue of the company for the year 2011 too dipped 13 percent reaching $1.32 billion.

The income from operations increased 4 percent to $800 million for the full year ended December 31, 2011, compared to $773 million for the same period of 2010.

''In 2012 we will be aligning resources behind key areas of focus to enable us to move aggressively in market and grow our business, bringing innovative new products and experiences to both our users and advertisers,'' said Scott Thompson, CEO, Yahoo.
