Microsoft made multiple attempts over several years to acquire all or parts of Yahoo, eventually reaching a 10-year search and advertising deal in 2009. This gave Microsoft an increased share of the search market from 8% to 12% and a large portion of search ad revenues from Yahoo sites. However, capturing even half of the total search market share was seen as unlikely as Google had already captured about two-thirds of the market through strong customer loyalty. The deal was seen as Microsoft getting significant benefits without an upfront payment, but some questioned if Yahoo gave up too much of its search business for the deal's value.
