Here are key events involving Yahoo Inc. and its performance in recent years:Nov. 17, 2008: Yahoo Inc. says co-founder Jerry Yang will step down as CEO as soon as a replacement is found. It ends a rocky reign marked by Yang's refusal to sell the Internet company to Microsoft Corp. for $47.5 billion, or $33 per share, in May 2008. Yahoo's board had been facing pressure to push him out as its stock plunged to its lowest levels since early 2003 and well below Microsoft's last offer price.Jan. 13, 2009: Yahoo names technology veteran Carol Bartz as its new chief executive, bringing in a no-nonsense leader known for developing a clear focus.Feb. 26: Yahoo announces a management shake-up. Chief Financial Officer Blake Jorgensen is pushed out, while Yahoo's chief technology officer and its top advertising executive in the United States get expanded duties.June 11: Yahoo hires a cost-cutting specialist, Tim Morse, as its new chief financial officer.July 29: Microsoft and Yahoo announce a 10-year search deal. Yahoo turns over responsibility for search technology to Microsoft, while Yahoo concentrates on sales of billboard-style advertising on the Web.Feb. 18, 2010: Regulators in the U.S. and Europe approve the search partnership.Oct. 7: Yahoo rolls out new tools to get people to the information they seek more quickly, especially when searching about entertainment, sports and major events. The hope is to distinguish itself from its Internet search partner, Microsoft, because Yahoo gets a cut of ad revenue when searches are done on its own site.May 10, 2011: Yahoo makes a surprise disclosure that Alibaba Group, one of China's most powerful Internet companies, had spun off its online payment service, Alipay. The split causes investors to re-evaluate the value of Yahoo's then-43 percent stake in Alibaba.June 23: Yahoo Chairman Roy Bostock seeks to defuse speculation about Bartz's job security at Yahoo's annual shareholders meeting, only to have it ignited again at the end of the session by an exasperated investor.Sept. 6: Yahoo fires Bartz after less than three years on the job. Morse, the chief financial officer whom Bartz lured from chip-maker Altera Corp., is named interim CEO.Jan. 4, 2012: Yahoo names Scott Thompson, president of eBay Inc.'s PayPal division, as Yahoo's new CEO, its fourth in less than five years.Jan. 17: Co-founder Yang leaves the company as he steps down from the board of directors. He had been on Yahoo's board since its 1995 inception.Feb. 7: Chairman Roy Bostock and three other longtime board members say they won't seek re-election to give Thompson an enhanced team of independent directors. Many Yahoo shareholders had been clamoring for Bostock to step down since the company balked Microsoft's 2008 takeover offer.March 25: Yahoo announces three new board members, gearing up for a proxy fight with one of its largest shareholders, Third Point LLC, which is trying to win four seats on Yahoo's board.March 28: Hedge fund manager Daniel Loeb, who controls a 5.8 percent stake in the company through his Third Point fund, blasts Yahoo's board appointments as "illogical."April 4 Yahoo announces plans to lay off 2,000 employees, or about 14 percent of its workforce. The cuts are part of an overhaul aimed at focusing on what Thompson believes are Yahoo's strengths while also trying to address its weaknesses in the increasingly important mobile computing market.April 6: Thompson unveils a plan to reorganize the company into three main divisions focused on users, advertisers and technology. Yahoo believes the new structure will improve users' experience with Yahoo, work closely with advertisers in different regions of the globe and strengthen the company's technology group.April 17: Yahoo reports first-quarter earnings, the first results under Thompson. Revenue grew less than 1 percent, but it's a breakthrough because the company's revenue has been steadily falling for years.May 3: Loeb, the disgruntled Yahoo shareholder, questions Thompson's qualifications and integrity after exposing a misrepresentation about the executive's education. Yahoo confirms that Thompson doesn't have a bachelor's degree in computer science from Stonehill College, as Yahoo previously stated. Thompson only has an accounting degree from Stonehill. Yahoo blames an "inadvertent error" and says its board will investigate.May 13: Thompson is out at Yahoo. Ross Levinsohn, who oversees Yahoo's media and advertising services worldwide, is named interim CEO.May 20: Yahoo agrees to sell half of its prized stake in Chinese e-commerce group Alibaba for about $7.1 billion. The deal calls for Alibaba to buy back half of the 40 percent stake that Yahoo owns in the Chinese company for $6.3 billion cash and up to $800 million of Alibaba preferred shares.

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 as Mayer tries to revive the company's revenue growth.Sept. 25: Software industry veteran Ken Goldman is named chief financial officer, replacing 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, 2013: 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.Wednesday: 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.
