Search Engine, Marissa Mayer | featured news

Yahoo (YHOO) announced its first acquisition under CEO Marissa Mayer on Thursday, a New York-based mobile startup named Stamped that was founded by two former Google (GOOG) employees and received financing from celebrities including Justin Bieber.

Yahoo Inc's new CEO Marissa Mayer sketched out her plan for revamping the mobile and search advertising business, outlining publicly for the first time her vision for getting the ailing Web company back on its feet.

Marissa Mayer, who earned a reputation for decisive action and intensity during her 13-year stint at Google Inc, has spent her first months as Yahoo Inc CEO quietly moving the Internet pioneer back to its roots in technology.

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.
