Yahoo has appointed 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.
Ms Mayer was one of Google's earliest employees and was most recently responsible for its mapping, local and location services. Ms Mayer, 37, began her career at Google in 1999 after getting her master's degree in computer science from Stanford, the school Google's co-founders attended.
Ross Levinsohn has been running the company on an interim basis and was thought to be the leading candidate after Hulu CEO Jason Kilar dropped out from consideration. Levinsohn filled in after Scott Thompson lost his job two months ago in a flap over misinformation on his official biography.
Fred Amoroso, Yahoo's chairman, says the board was drawn to Ms Mayer's "unparalleled track record in technology, design, and product execution".
Within a few months, Ms Mayer expects to be on a maternity leave. She revealed to Fortune magazine that she is pregnant with a boy and her due date is October 7. Ms Mayer said she had informed Yahoo's board about her pregnancy before the 11 directors unanimously voted to hire her.
Yahoo's website remains among the most popular destinations on the internet with 700 million monthly visitors, but the company has struggled to turn those visits into ad revenue growth. Yahoo's decline has been exacerbated by the success of internet search leader Google and social networking leader Facebook.
Levinsohn, 48, who once ran internet services at News Corp, made a positive impression by closing a long-delayed deal to sell part of its stake in Alibaba Group, one of China's most successful internet companies. He also negotiated a truce with Facebook, averting a legal fight over patent rights that threatened to poison Yahoo's partnerships with the social network.
Ms Mayer has a list of talents and accomplishments that could serve Yahoo well. She gained a reputation at Google as an effective leader with a long string of successes. Known for a folksy demeanour that harks back to her roots in Wausau, Wisconsin, she is a maths whiz with a photographic memory. In her time at Google, she led teams that produced many of the company's most recognisable products, including the development of its flagship search product and the iconic Google homepage.
Mayer managed the launch of more than 100 features and products including Google News, and Gmail. She is credited with overseeing the creation of much of the clean, uncluttered "look and feel" of many Google products.
"I'm incredibly excited to start my new role at Yahoo," Ms Mayer wrote to friends and followers on Twitter.
