Microsoft, the company that defined the PC, is still enormously profitable — but not as profitable as it once was.

This week, Microsoft will try to regroup. It is rolling out the largest upgrade of its Windows software in more than a decade. All of this is meant to help the company break into the exploding market for mobile.

While the company still commands a formidable computing empire, it is now under attack.

Microsoft's CEO is Steve Ballmer, a big, bombastic, balding guy. These days he's riled up about Windows 8.

High school was not a particularly awesome time in the life of Arthur J. O'Connor. That social fairy dust that some people seem to have? He didn't have it.

"I was a wallflower. I was a nerd," O'Connor says. "I was incredibly intimidated by everybody."

The Libertad, a ship owned by the Argentine Navy, set sail across the Atlantic a few months ago. It was being tracked, via the Internet, by a U.S.-based hedge fund called NML Capital.

At Monday night's foreign policy debate, the first round of questions for the presidential candidates will involve "America's role in the world."

The answers from President Obama and former Gov. Mitt Romney likely will focus on military readiness and anti-terrorism efforts. That's what most Americans would expect to hear, given that their country has been involved continuously in overseas combat since the terrorist attacks of 2001.

Video game makers are rolling out their new titles — with a wide range of creativity and style — just in time for the holiday shopping season. Jamin Warren, founder of Kill Screen magazine, shares his list of video games you should keep your eye on:

In a sterile white boardroom in ABC Family's headquarters in Los Angeles, two young women are assiduously ignoring a spread of cookies in favor of two more important things: their laptops and a live broadcast of the show Pretty Little Liars playing on a large flat-screen TV.

Dalia Ganz, 28, is the show's social-media manager. She's patiently teaching one of the beautiful young actors on the show how to live-tweet this episode.

"Include #prettylittleliars in your answers," she instructs. That is a literal transcription of her words.

While most American homes still have a television in the den, how we watch, and what we watch, is changing. Computers, tablets, smartphones, DVRs and video game consoles have redefined what television is.

Viewers have officially become a multiscreen culture. And that means the TV industry is changing, as well. Consider that 36 million Americans watch video on their phones, according to the Nielsen ratings company.

Most of us know someone who's had a hard time finding or keeping a job over the past few years. It's an experience that often leaves people feeling defeated and demoralized. In Weekend Edition Sunday's Working It series, hear audio portraits of people whose daily lives are filled with uncertainty.

It's not just nutritionists who have a problem with sugar these days, so does organized labor. The AFL-CIO is calling for a boycott of one the country's biggest sugar producers, the American Crystal Sugar Company, based in Moorhead, Minn.

There was a 1.7 percent drop in sales of existing homes in September from August, the National Association of Realtors says.

But the median selling price compared to one year earlier was up for the seventh month in a row, leading NAR chief economist Lawrence Yun to say "we're experiencing a genuine recovery."

According to NAR:

When our series began yesterday, we brought together five economists from across the political spectrum and had them create a platform for their dream presidential candidate. It's a platform — Get rid of a tax deduction for homeowners!

In many large cities, like Dallas, Phoenix and even parts of Chicago, $800 a month is enough for a clean one-bedroom apartment, decked out with a living room, washer and dryer — and maybe even a pool, in a larger complex.

But if you want to live alone in San Francisco, getting those amenities at that price is practically a pipe dream. With the region's resurgent high-tech industries luring many well-educated, well-paid workers to the Bay Area, the average rent for a studio apartment in the city now runs around $2,000.

Newsweek editor Tina Brown announced Thursday she would embrace a fully digital future as she revealed that the magazine's final print edition would be published at the end of the year.

Her announcement was a bow to gravity, as her unique blend of buzz and brio proved incapable of counteracting Newsweek's plummeting circulation and advertising amid an accelerating news cycle. Brown said there would be an unspecified number of layoffs as well.

If you're one of those people who vigilantly checks the ingredient list of the things you buy at the grocery store, you may have already seen this: Some food products now contain something called "evaporated cane juice." It can be found in yogurt, fruit juices and lemonades.

So what exactly is evaporated cane juice? Well, it depends on whom you ask. We spoke with a few folks outside our local grocery store, and many of them were confused. Take a listen:

Oops.
