Marissa Mayer, now one of Silicon Valley's most powerful female executives, starts her new job today as CEO of Yahoo. Marissa Mayer was employee #20 at Google, and a top executive there. Now, she's among the few women to break the glass ceiling in the male-dominated tech sphere, joining the ranks of Cheryl Sandburg of Facebook and Meg Whitman of Hewlett Packard.
Marissa Mayer also happens to be pregnant, and is expecting her first child in October. That fact is causing some buzz about her appointment. Not only is she likely to be judged on the daunting task of turning around Yahoo, a struggling online mega-brand, women will be watching closely to see how well she's able to balance the challenges of the boardroom with her new role as a working mother. Mayer herself has struggled with the work-life balance. During her early days at Google, she apparently often slept at her desk, routinely pulling all nighters.
