CEO Marissa Mayer marks her one-year anniversary at Yahoo this week. Here are key events involving Yahoo Inc. and its performance since she was appointed:
— July 16, 2012: Yahoo names longtime Google executive Marissa Mayer as its fifth CEO in as many years.
— July 17: On Mayer's first day on the job, Yahoo reports lackluster quarterly results, underscoring the challenges she will face.
— July 30: Yahoo announces Ross Levinsohn is leaving the company. He served as Yahoo's interim CEO but lost to Mayer for the permanent appointment.
— Sept. 18: Yahoo completes a long-awaited, $7.6 billion deal for Chinese e-commerce company Alibaba Group to buy back half of Yahoo's 40 percent stake. Most of the proceeds will go to its shareholders, but Yahoo still has an extra $1.3 billion to finance acquisitions or hire new talent.
— Sept. 25: Software industry veteran Ken Goldman is named chief financial officer, replacing Tim Morse, as Mayer moves swiftly to build her senior management team.
— Oct. 22: In the first quarter under Mayer, Yahoo reports third-quarter results that topped analyst estimates. Yahoo's net revenue barely grew at a time when advertisers are spending more money marketing their products and services online. Nevertheless, the numbers were slightly better than analysts projected.
— Jan. 28, 2013: Although Yahoo still isn't keeping pace with the overall growth of the Internet ad market, the company says it fared well enough during the fourth quarter to produce its first full-year gain in revenue since 2008. It was a scant increase: just $2.4 million higher than 2011's total of nearly $5 billion.
— Feb. 12: Mayer tells an audience of investors that Yahoo will be better served with just 12 to 15 mobile applications, down from a "scattered" portfolio of as many as 75 different programs in recent years.
— Feb. 20: Yahoo unveils a long-awaited makeover of its home page to get people to visit more frequently and linger for longer periods of time. It's the first time Yahoo has redesigned the page in four years. Yahoo says it has developed more sophisticated formulas to determine which topics are most likely to appeal to different people so the news feed can be fine-tuned to cater to different tastes.
