Last July, we presented the agreement forged between Microsoft and Yahoo who asked only to be approved by regulators to enter into force. Thus, this agreement should be permanently sealed last October 27, but the validation procedures have taken longer than expected and the two giants have announced the postponement of their agreement in early 2010 because they want to finally take the time to tuning some details.

"There are still issues that need to be clarified, it is very complex" simply stated a representative from Yahoo. However, both sides make clear that nothing is questioned in the background, and Yahoo will handle much of the marketing of advertising time when Microsoft is going to develop the search function.

A partnership that would allow Microsoft and Yahoo compete with Google AdWords and very profitable. For Carol Bartz, CEO of Yahoo, the objective of this partnership is to break the "monotony of the market for online advertising" dominated the head and shoulders by Google.
