Yahoo has suffered another hack. The company disclosed today that it has discovered a breach of more than one billion user accounts that occurred in August 2013. The breach is believed to be separate and distinct from the theft of data from 500 million accounts that Yahoo reported this September.

A prominent local media executive fired from Yahoo last year has filed a lawsuit alleging the firm’s CEO Marissa Mayer led a campaign to purge male employees and replace them with women.

Yahoo Inc last year secretly built a custom software program to search all of its customers' incoming emails for specific information provided by U.S. intelligence officials, according to people familiar with the matter. The company complied with a classified U.S. government directive, scanning hundreds of millions of Yahoo Mail accounts at the behest of the National Security Agency or FBI, said two former employees and a third person apprised of the events.

A recent investigation by Yahoo! Inc. (NASDAQ:YHOO) has confirmed that a copy of certain user account information was stolen from the company’s

In a statement released today, Yahoo said a hack of its network in late 2014 breached information related to at least 500 million user accounts

You're desperate to be a success, aren't you? What else is there in life? If you can't waft into a fancy restaurant and turn heads with your sense of net worth, who are you? How do you get there, though? Malcolm Gladwell would have you believe that you must spend 10,000 hours working at something before you can be truly world class. Though some think this might be truly nonsense. We now have a new definition from Marissa Mayer.

Hulu inks deal with Yahoo to provide free, ad-supported episodes of TV shows. Hulu is moving to an all-subscription model, eliminating the ad-supported service that has let users watch thousands of TV episodes in the nine years since it first launched. At the same time, Hulu has expanded its distribution deal with Yahoo, which is launching Yahoo View, a new ad-supported TV-streaming site with the five most recent episodes of shows from ABC, NBC and Fox — eight days after original air date — as well as other network shows, day-after clips, and full seasons...

It’s more than double what has been previously reported and far more than the company is saying. After the Verizon VZ 0.51% deal was announced on Monday, the Internet erupted in outrage that Yahoo CEO Marissa Mayer could collect as much as $55 million. That’s the figure Yahoo YHOO -0.15% stated in April that Mayer could collect if the company were sold and more-than enough to get observers who think Mayer has not done a great job to declare her pay unfair, and another sign that corporate compensation is corrupt.

There was a time when Yahoo was the internet company that Google is now. What happened?

US telecoms giant Verizon Communications is to buy Yahoo's search and advertising operations for $5bn (£3.8bn), according to media reports. The two firms were reported on Friday to be in exclusive talks over a possible deal. US internet firm Yahoo announced in February that it was looking at "strategic alternatives" for its core internet business. Verizon declined to comment on the reports. A formal announcement is expected on Monday before US markets open for trading.

Yahoo Inc is focused on selling its core business to U.S. telecommunications company Verizon Communications Inc after reviewing final bids that it received this week, people familiar with the matter said on Friday. A deal would boost Verizon's AOL internet business, which it acquired last year for $4.4 billion US, by giving it access to Yahoo's advertising technology tools, as well other assets such as search, mail, messenger and real estate.

Marissa Mayer may be ending her tenure at Yahoo on a sour note. Yahoo is writing down the value of its Tumblr acquisition by $482 million, citing lower projections for the social network's future performance, the company announced Monday. This comes after Yahoo (YHOO, Tech30) took a $230 million similar writedown last quarter on its Tumblr buy. In total, Yahoo has now written down more than half of Tumblr's value since acquiring it for $1.1 billion in 2013 -- rendering Mayer's biggest acquisition to date effectively worthless.

Back in the mid-1990s, before Google even existed, the world’s best guides to the internet sat in Silicon Valley cubicles, visiting websites and carefully categorizing them by hand. They were called surfers, and they were a collection of mostly 20-somethings — including a yoga lover, an ex-banker, a divinity student, a recent college grad from Ohio hungry for adventure — all hired by a start-up called Yahoo to build a directory of the world’s most interesting websites. Today, with more than one billion websites across the globe, the very notion seems mad. Even then, there was a hint of insanity about the enterprise.

There was a time, at the advent of the World Wide Web, when Yahoo was a big deal. As websites proliferated, two Stanford grad students, Jerry Yang and Dave Filo, created a directory of sites that they recommended. They called it “Jerry and David's Guide to the World Wide Web.” They later renamed it “Yahoo!”. As the Internet exploded during the 1990s, so too did Yahoo.

Yahoo Inc. chief Marissa Mayer will walk away with a $55-million severance package if the company's auction of its Internet operations culminates in a sale that ousts her from her job. The payout disclosed in a regulatory filing Friday consists of cash, stock awards and other benefits that Mayer would get should she be forced out as chief executive within a year after a sale.

Yahoo is for sale, and bidders are lining up to grab their own, ever-shrinking piece of Internet history. The once-great Internet pioneer is entertaining offers...reluctantly. CEO Marissa Mayer would like to see Yahoo through its struggles, but impatient investors are looking for a way to cash out. Yahoo (YHOO, Tech30) has reportedly given interested parties until April 18 to make their offers. The company is expected to fetch something like $8 billion for its core Internet business.

Yahoo is one of the best-known brands on the internet, but its core internet business is in a grim situation. How grim? There's a debate over whether the company itself — what most of us think of when we think of Yahoo — is actually worth less than zero dollars. Back in 2005, Yahoo invested $1 billion in one of China's hottest technology startups, Alibaba, getting a roughly 40 percent stake. The bet has paid off handsomely.

With an auction process nearing and a possible proxy battle looming, it looks increasingly likely Yahoo will not remain a standalone, publicly-traded company one year from now. Yet its chief executive is calling for three more years. Marissa Mayer, in a one-hour interview Thursday night with Charlie Rose, revealed that she has a “three-year strategic plan” for continuing on in her attempt to turn around Yahoo that entails...

Yahoo, which has been losing money on most of its high-profile online video efforts, said it reached a deal to stream live NHL hockey games for free. The games are in addition to NHL games currently offered on Yahoo through its partnership with NBC Sports Group. In addition to live games, Yahoo will provide condensed games and highlight packages. Financial terms of the deal were not disclosed.
