Yahoo Just Can't Escape the Marissa Mayer Disaster

The Marissa Mayer disaster rolls on for Yahoo. 

After she failed to get the job done, the Board essentially forced a sale out from under her.  But now even that might be cratering.

Verizon's general counsel, Craig Silliman, said on Thursday the company has a "reasonable basis" to believe that Yahoo's massive data breach of at least 500 million email accounts represents a material impact that could allow Verizon to withdraw from its $4.83 billion deal to buy Yahoo.
