Yahoo! surprised everyone by announcing the name of Marissa Mayer, as its new CEO; the lady who had been a part of Google for 13 years. Mayer was positioned as vice president of location services at Google before she left the job to join Yahoo!.

Marissa Mayer confirmed resigning from Google and becoming a part of Yahoo! while speaking to Dealbook’s Aaron Ross Sorkin. She will take over interim Chief Executive Ross Levinsohn to become Yahoo!’s second female CEO.

Ever since Carol Bartz was removed from his post as CEO of Yahoo!, the company has had four chief executives over a span of one year. Though, this time everyone expected Levinsohn to stay for long specially after he successfully launched Yahoo!’s mobile Axis browser and settled a high-profile patent lawsuit with Facebook in the short period of time that he had.

On Mayer’s leaving Google, Larry Page, CEO of Google wished her farewell by releasing a statement stating: “Since arriving at Google just over 13 years ago as employee #20, Marissa has been a tireless champion of our users,” Page said. “She contributed to the development of our Search, Geo, and Local products. We will miss her talents at Google.”

At Google, Mayer handled various important projects to success and she hopes to deliver what is expected of her at Yahoo! too.

On her achievement of becoming a part of Yahoo!, she said, “Yahoo!’s products will continue to enhance our partnerships with advertisers, technology and media companies, while inspiring and delighting our users. There is a lot to do and I can’t wait to get started.”
