Marissa Mayer was a top executive and employee number 20 at Google, so she was pretty close to that top of that Googleicious (is that a word, if not, it is now) tree. Mayer was the Vice President of Local, Maps and Location Services and has just jumped ships.
She's jumped over to Yahoo, and will serve as the CEO of Yahoo. Quite the jump. Mayer joined Google back in June of 1999, and was Google's first female engineer, where she remained employed until her resignation earlier today.
Mayer's move to Yahoo spells good things for the company, as she sports a degree in computer science, and all that time at Google. But, compared to the competition, Yahoo has been struggling lately. Can Mayer swing it around?
