New Delhi: Young, powerful, rich, and brilliant, Yahoo CEO Marissa Mayer is a role model for millions of women. Now 38 years old, she is a wife, a mother, an engineer, and the chief executive of a $30 billion Yahoo, a woman in an industry dominated by men.It has been a year since Marissa Mayer assumed command of Yahoo, and there's no doubt that she's injected the much required energy into the purple-hued Internet pioneer. Mayer has revamped many of Yahoo's core products, like Flickr, embarked on an ambitious acquisition spree — including the blockbuster $1.1 billion purchase of Tumblr — and returned hundreds of millions of dollars to shareholders. Perhaps most important, Mayer has rejuvenated esprit de corps among the company's long-suffering employees.Given the bad shape Yahoo was in when Mayer took over as CEO, her most important accomplishment has been to get people talking positively about Yahoo again. Mayer has been pushing Yahoo's developers and designers to make improvements to the Sunnyvale, California-based company's products and services since she was hired in July of last year from Google. She revamped the home page, e-mail and weather services with sleeker designs and other improvements. Moreover, the company's stock price is up 100 per cent and engineers wanted to work for Yahoo again. More users will lead to better financial results, she said in July. Recently, ComScore Inc. announced that over 196 million Web users spent time on the largest U.S. Web portal's sites during the month, up 21 per cent from a year earlier.From Wall Street to Silicon Valley, there are people hoping for her success at Yahoo top spot.

Mayer adopted a concept from her days at Stanford—office hours. For about 90 minutes a day, beginning at 4:00 pm, Mayer used to hold office hours at Google. Employees would add their name to a board outside her office and, on a first-come basis, would get a few minutes of her time.

People at Google credit her with the success of not just Google search, but also many others, including Gmail, Google Maps, and Google News.Got demoted at GoogleHer attention to detail may have been too much for even Google to handle. In an unauthorised biography of Yahoo! CEO Marissa Mayer, Business Insider journalist writes that though Mayer did extremely well at Google where she designed its homepage, created its product management structure and "became the face of the company", she was demoted between 2010-2012 due to public disagreements with colleagues.Is instrumental in Yahoo's turnaroundAfter joining Yahoo, a major challenge for Mayer was to pump new energy into the purple-hued Internet pioneer. Mayer has revamped many of Yahoo's core products, like Flickr, and has embarked on an ambitious acquisition spree — including the blockbuster $1.1 billion purchase of Tumblr — and returned hundreds of millions of dollars to shareholders. Under her leadership, Yahoo also topped Google as the most-visited website in the United States in July. Yahoo received 196.6 million unique visitors during the month, compared with 192.3 million for Google. This was for the first time Yahoo has found itself in the top spot for U.S. Web traffic since May 2011.

She gave the news exclusively to Fortune, but the word starting spreading like wildfire seconds after it went public. She set a precedent as the first woman to ever take the top position while pregnant. And, in late September, when she had her first child, she only took a couple weeks off for maternity leave. Yahoo! announced that Mayer is working from home this week but she may reappear in the office in person after only a week of maternity leave. The self-described geek prompted much debate about how pregnancies affect women in the workplace. However, in a striking announcement, Mayer demanded that all remote employees report to office facilities by June 1. Her decision elicited a flood of opinion from both sides—those who agree with CEO Marissa Mayer and Yahoo's HR chief that “communication and collaboration” are required for innovation to flourish and others who say Yahoo's ban on working from home is a throwback to the stone age.Has a fly penthouse It's atop the Four Seasons Hotel in San Francisco, and it's worth a cool $5 million, according to The New York Times.Likes cupcakesMayer likes them so much that the Google exec once created a spreadsheet to maintain a detailed record of the ingredients that go into her favorites.A fashionista Mayer is obsessed with fashion.
