For News Corp. (NWS), MySpace is the mistake that keeps on costing. It's bad enough that Murdoch's empire paid $500 million for the social networking platform shortly before Facebook knocked it from the premier spot in the social media beauty pageant, but now we also know that News Corp. has committed $350 million to office space for MySpace that will never be used.

News Corp is shelling out more than $1 million a month for 420,000 square feet in Playa Vista, near Los Angeles International Airport. The deal was signed in August 2008 by Peter Levinsohn, former president of the Fox Interactive Media Unit. At the time, he issued a chest-puffing memo claiming it was "the single biggest real-estate transaction in Los Angeles in the last 25 years." Fortunately, he didn't mix the word "genius" in there at all.

If Amazon (AMZN) was comfortable with its spot atop the e-reader market, it just got a wakeup call from Barnes & Noble (BKS). The brick-and-mortar book retailer's e-reader, the Nook, which hasn't even hit stores yet, is in pre-order nirvana right now. The first run for the Nook occurred at the end of October (the product was introduced on October 20). These buyers were told the reader would ship on November 30. High demand resulted in backorders, so the next wave of pre-orders was scheduled to ship on December 7. Now, a third group will have to wait until December 11.

This product is on fire, and it still isn't even on shelves yet.

Mary Ellen Keating, a spokeswoman for Barnes & Noble wouldn't reveal how many of these devices have been pre-ordered, but she did say, "Demand for the product in our stores and online has surpassed our expectations." She also noted, "We are working hard to meet demand for the holidays."

The Twitter ecosystem may be changing constantly, but most of that comes on the back of individual developers and outside companies. They beat on Twitter APIs to create new products that may win them glory, recognition or cash. Over the past month, though, Twitter itself has gotten into the game, releasing or announcing a handful of new features.

A new function for "retweeting" (echoing another's tweet to your own followers), changes to how trending topics are managed, and the ability to create lists are new tools intended to engage users ... on the Twitter.com website. Considered within the context of Twitter's changed terms of service this year, the upgrades may be part of a broader ad-based revenue plan.

While Sprint Nextel Corp. (NYSE: S) continues losing hundreds of thousands of customers every quarter, it has actually raised the bar on offering cutting-edge smartphones at the same time. Smartphones, which are slowly but surely replacing the standard cellphone for the typical "always need to be connected" consumer, are helping wireless carriers drum up wireless data revenue to replace the lost voice revenue as customers talk less.

The latest litigation has Intel Inside.

The State of New York is going after Intel (NASDAQ: INTC) over antitrust allegations. State Attorney General Andrew Cuomo is accusing the largest chip manufacturer in the world that it is trying to secure a global monopoly for microprocessors.

For several years, Cuomo said that Intel has pushed the likes of Dell (NYSE: DELL) and Hewlett-Packard (NYSE: HPQ) to agree to the exclusive use of Intel's gear in exchange for billions of dollars in payments. The hefty cash outlays have given what Cuomo called a "stranglehold" on the market.

While eBay (NASDAQ: EBAY) has been working hard to manage its marketplace in a trying economy, its PayPayl business has been growing comfortably and could become the company's biggest earner. For the past two years, eBay has focused on improving the look of its website and helping buyers and sellers to get along in a virtual world built entirely on trust.

In the background, though, the segment of the business that moves money from Point A to Point B has been on fire. Even with payment processing competition from Amazon (NASDAQ: AMZN) and Google (NASDAQ: GOOG), PayPal has been able to do more than hold its own.

Google Inc.'s (NASDAQ: GOOG) Google Apps project has gained steam (and customers) since its introduction a few years ago. Although it's not yet a true competitor to Microsoft Corporation's (NASDAQ: MSFT) Office juggernaut, it is making headway.

The "software as a service" camp is doing nothing but speeding up, as small and large businesses would like to offload expensive software installations and just use the Internet as a vehicle for getting things done across boundaries and time zones. Microsoft, though, is not capitulating just yet.

Founded in 1999, TeleNav was one of the first companies to deploy GPS navigation on a cell phone in North America. Now, the company has more than 11 million paying end users.

What's next? TeleNav has filed for an IPO.

The flagship of the company is the GPS Navigator, which is more than just a GPS device with cool features like real-time traffic alerts, weather content, route-planning and so on.

Google, Inc. (NASDAQ: GOOG) recently has had a knack for releasing software products that challenge -- and even threaten -- entire industries. Take, for example, last week's enhancement to Google Maps, which caused the stock prices of GPS companies TomTom and Garmin to plummet after Google announced its own GPS service that, in many ways, was a superior product. Yes, it's free with a Google-powered phone.

What's next? How about real estate listings?

An article in Barron's suggests that Motorola (NYSE: MOT) is on the verge of regaining some of its former mojo. The company recently offered a solid outlook for the remainder of the year, and it could garner new business after debuting two smartphones featuring Google's (NASDAQ: GOOG) Android operating system -- namely, the Droid and the Cliq.

The author cites analyst Ed Snyder of Charter Equity Research, who believes Motorola is on the cusp of "an extended upswing in handsets ... over the next several quarters." Snyder believes that the firm's ailing handset division could achieve break-even results as soon as the second quarter of 2010.

Although Microsoft Corp. (NASDAQ: MSFT) has much of the business world wrapped around at least some of its software, the largest software company in the world is mostly known for its consumer products. Names like Windows, Zune, Windows Mobile, Sidekick, and Xbox are household terms (well, in gadget households perhaps).

Still, with all those names, why hasn't Microsoft formed some kind of overall consumer ecosystem so that all these products fit, work, and play together seamlessly?

Google (NASDAQ: GOOG) makes it easier to search for websites, e-mail messages, passages from books and videos. Where you haven't heard much about Google's search capabilities -- or Google in general -- is the music business.

But, that's about to change. On Wednesday, the search giant announced that it was partnering with music services such as Pandora, Lala, News Corp's (NASDAQ: NWS) MySpace, and Rhapsody by RealNetworks (NASDAQ: RNWK) to help users find, listen to and ultimately buy music on the web.

RealNetworks (NASDAQ: RNWK) is profitable again! The online media company that provides music and other entertainment cut its way into the black, getting rid of the costs that were getting in the way. It wasn't much of a profit, only $1.5 million for the third quarter, not even a full cent per share, but it's a hell of a lot better than the $4.5 million loss it sustained in the third quarter of 2008.

Revenue fell 8% last quarter to $140.3 million, just shy of the analyst average of $140.9 million. This trend is likely to continue through the fourth quarter. Music, technology product and game revenues were down. The profit was instead eked out of the supply chain and headcount.

Google Inc. (NASDAQ: GOOG) just keeps on rolling out products that are keen on competing with established industries. The internet search giant now wants you to replace your cellphone number with only your Google Voice number. That's right -- replace your cellphone number and voicemail service with the Google Voice service and have all those voicemails transcribed to you and emailed or texted to yourself.

While Symantec (NASDAQ: SYMC) is the biggest player in security software, it has been lagging over the past few years. But, the company has been taking action, especially in revamping its sales organization.

And, it seems to be working. Today, Symantec reported its Q2 results, which showed a 19% increase in net income to $150 million or $0.18 per share. Yet, sales were still soft, declining 2.9% to $1.48 billion (but it was still better than the $1.43 billion consensus forecast).
