In a recent interview with Reuters, Yahoo chief exec Marissa Mayer said that the company's partnership with Microsoft's Bing search engine is not producing the market share that was expected.

In 2010 Yahoo and Vole signed a 10 year contract in an effort to steal some search engine market share from search giant Google. From the looks of things, what actually happened was Microsoft and Yahoo actually ended up just trading that market space with each other.

In December 2012, Yahoo owned about 12% share, with Microsoft having just over 16%. Two years ago before the deal took place the numbers were flipped around almost exactly with Microsoft having 12% and Yahoo owning 16%. While Meyer is not happy with the numbers, it does not mean that she wants out of the partnership, she just would like to see improvements made.
