Yahoo just fired its CEO of 2 1/2 years.
In 2008, Yahoo founder Jerry Yang turned down a buyout from Microsoft worth $44bil. He was continuing to build and expand the company and thought the offer was undervalued. This set off a squabble among the board of directors, throwing all existing plans into doubt and severely hampering the company.
A year later, he was removed and replaced by Bartz - a prototypical business manager, not a visionary. This was merely a continuation of the business-centric uproar started when Yahoo didn't sell out to Microsoft.
One of the first moves of Bartz was to sell of a piece of Yahoo's search to Microsoft for pennies. She then proceded to 'reorganize' of slash, consolidate and burn all the expansion and future Yang had laid out. Now, 2 1/2 years after taking control and implamenting business-savy over business-vision, Yahoo is only worth around 1/3 what Microsoft was offering and in a death spiral.
After a few months of looking for a replacement for Bartz, she was fired and a temporary, in-house CEO took control to try and immediately mend finances. Essentially, Yahoo has gone from a growing powerhouse to intensive care since replacing it's founder. The same happened to Apple the first time it fired Steve Jobs and I have no reason to doubt it won't happen again.
