It appears that internet giant Yahoo is shifting away from the search arena and looking more towards mobile services, content and display advertising, and has now sold their search business to Microsoft reports an article on The New York Times.

The reason given is Yahoo can no longer match the level of investment being made by Microsoft and Google in the search arena according to Carol Bartz the CEO of Yahoo.

However the move from search related marketing means Yahoo can now focus spending on other areas such as mobile and display advertising.
