Yahoo CEO Marissa Mayer gave birth to a boy late Sunday Sept. 30, 2012, casting a spotlight on her ability to steer the struggling Internet company in a new direction while adjusting to the challenges of being a first-time mother. The birth came a week ahead of the Oct. 7 due date that Mayer shared with the public in July. She announced her pregnancy on her social networking accounts just a few hours after Yahoo hired her as its third full-time CEO in less than a year. (AP Photo/Evan Agostini)
