There have been high hopes for Mayer ever since she came to Yahoo in 2012 to take over as CEO. But the former Google executive?s tenure has been rocky at the company. On Monday, July 25, 2016, Verizon formally announced that it is buying Yahoo for $4.83 billion, marking the end of an era for a company that once defined the internet. (AP Photo/Eric Risberg, File)
