The rise and fall of Marissa Mayer, from the once-beloved CEO of Yahoo to a $4.48 billion sale to Verizon

Hopes were high when Marissa Mayer was hired as CEO of Yahoo in 2012. People thought she would turn around the perennially dysfunctional internet giant.

Five years years later, and Mayer's time at Yahoo was marred by slowing growth and internal dissent, leading to plummeting employee morale and calls for her resignation. Plus, under her watch, Yahoo experienced historically large security breaches that placed millions of customers at risk.

Today, the Mayer era comes to a close, with Verizon's $4.48 billion purchase of Yahoo fully finalized. Now that the deal is officially done, Mayer is officially out as CEO. She will not join the combined Yahoo/AOL entity that will be called "Oath," either.

We went through a bunch of recent news stories and Nicholas Carlson's book - "Marissa Mayer and the Fight to Save Yahoo!" - to put together the story of Mayer's epic rise to become one of the biggest Silicon Valley power players, and her sudden fall from grace.
