In its continual struggle to catch up to rival Google, Yahoo must find new ways of doing a business that it helped create.  While once the leader of internet search, Yahoo has fallen behind Google over the past few years and is now racing to regain lost market share.

According to senior vice president Brad Garlinghouse, that struggle can only be won by a complete ground-level restructuring of the company and its operations.

In an internal company memo released by the Wall Street Journal, Garlinghouse said that the company suffered as a result of no clear focus or strategy.  Using a peanut butter analogy, he describes the company as spread to thin - Yahoo tries to be all things to all people.

To rectify the problem, Garlinghouse is suggesting a reduction in Yahoo's workforce of 15 - 20 percent and a refocus of the company's attention to a few key areas, including video, mobile, and social networking.  In addition, he argues that the company needs a "radical restructuring" to define who is in charge and what departments should each focus on.

Over the past week or so we've seen Yahoo move aggressively into mobile advertising and social networking.  The memo published in the Journal was written last month.  Could these emerging media pushes be the first signs of the new Yahoo?  What better way to see where Yahoo is and where it needs to go than a memo written by Yahoo and for Yahoo.

While the details of the memo's impact on the company are still unclear, one thing isn't:  Yahoo has a lot of ground to cover if it wants to de-throne Google.
