Google, Marissa Mayer | featured news

Yahoo named Henrique de Castro, a Google ad executive, as its new chief operating officer, deepening Chief Executive Marissa Mayer's stamp on the company.

Marissa Mayer's move from Google exec to Yahoo! CEO made her one of the most powerful women in the tech industry. Her announcement just three hours later that she's expecting her first child made her "the most powerful pregnant woman in America," says Lisa Belkin of The Huffington Post.

Yahoo is hiring longtime Google executive Marissa Mayer to be its next CEO, the fifth in five years as the company struggles to rebound from financial malaise and internal turmoil. Mayer, who starts at Yahoo Inc. on Tuesday, was one of Google's earliest employees and was most recently responsible for its mapping, local and location services. Mayer, 37, began her career at Google in 1999 after getting her master's degree at Stanford, the school Google's co-founders attended.
