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.

Who needs venture capital money when you have litigation? Facebook was awarded $711 million in damages Thursday in an anti-spam case against Sanford Wallace, an internet marketer. The popular social networking platform went after Wallace for tapping its users' accounts without their permission and sending fake posts and messages.

Wallace has quite a reputation for spamming, having gained the nicknames "Spam King" and "Spamford" back in the 1990s, when he was good for up to 30 million spam e-mails a day.

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.

Your e-mail account is a goldmine. Technology companies push hard to keep your data secure, but there are plenty of scumbags out there who always seem to find a new way to gain an edge over the guys in white hats. Phishers, in particular, are eager to find new ways to profit from your identity and information, and they're getting some new tricks.

Phishing scam activity was quiet at the beginning of this year, according to a report in USA Today, but these attacks surged 200% from May through September, says the X-Force team at IBM (NYSE: IBM). Webmail, social media and gaming accounts are their primary targets. E-mail access, in particular, is highly sought after, since they can be use to push out spam ... while bypassing filters.

These "virgin" e-mail accounts command top dollar: a digital criminal can pick up as much as $2 for a clean account from Microsoft (NASDAQ: MSFT) Windows Live, Google (NASDAQ: GOOG) Gmail, Yahoo (NASDAQ: YHOO) YahooMail or AOL (NYSE: TWX). This is more than twice the amount typically paid for a stolen credit card account, according to Fred Rica, principal in the security practice at PricewaterhouseCoopers. Many webmail users actually do half the criminals' job for them, with 33% using just one password online and 48% using only a handful.

It was still a good idea for News Corp. (NASDAQ: NWS) to buy MySpace.com over fours years ago for a little more than half a billion. The social media network still brings in decent ad revenues, even though it is out of the popular fad culture of social media. That space is now owned by Facebook and Twitter. But then MySpace CEO Owen Van Natta says that his company is "fundamentally different" than Facebook -- as in a special experience providing entertainment content -- those words could come back to haunt him.

As will words like "I really don't view Facebook as a competitor." While it's true that Facebook and MySpace go after two types of online social interaction, they are both vying for many of the same customers in a large crossover audience. Teens, 20-somethings, and others are very fickle and many use both social networks. The two may have different goals, but they are competitors.

A new executive team is trying to bring MySpace back to its former glory. By focusing on music, videos and games, it hopes to recapture some of its luster. With the MySpace refugees mounting, it's time for some new blood to make some brilliant, future-changing decisions. This week, the company is holding a conference for its global ad sales team to explore ways to bring in traffic and beef up ad spending.

MySpace is poised to haul in $495 million in ad revenue this year, down 15% from last year's $585 million, according to research firm eMarketer. In August, MySpace attracted 64.2 million unique visitors from the United States, off 15% from August 2008, according to comScore, while Facebook pulled in 92.2 million unique U.S. visitors – up more than 100% year-over-year.

Have you ever looked at your Yahoo! (NASDAQ: YHOO) Flickr account and thought, "Why am I doing this? I can just throw my pics up on Facebook"? If this has crossed your mind, you're not alone. In fact, many photo-sharing sites – Snapfish (NYSE: HPQ), Photobucket, Picasa (NASDAQ: GOOG) and Shutterfly, as well as Flickr – are asking the same questions. With the development and enhancement of photo management capabilities in major social networking websites, niche players need to find new ways to stay relevant.

The situation is still far from grim. Fed by traffic from their behemoth owners, the photo-sharing sites remain substantial forces, and they are currently home to more than 20 billion pictures. There's still plenty of interest in these environments ... which has been bolstered by specific features that make the likes of Flickr attractive to both professional photographers and amateur shooters. The ability to order prints and personalize portfolios, for example, still provides an edge over sites like Facebook and MySpace (NYSE: NEWS).

Nonetheless, the threats from the social networking space are quite real.

News Corp. (NASDAQ: NWS), a media company that competes with Disney (NYSE: DIS), General Electric's (NYSE: GE) NBC Universal, Sony (NYSE: SNE), CBS (NYSE: CBS), Time Warner (NYSE: TWX), and Viacom (NYSE: VIA), reported Q4 earnings on Wednesday after the bell. They were unimpressive. Revenues decreased almost 11%. On a reported basis, the company lost 8 cents per share, compared to a profit of 43 cents per share in the year-ago period. That is a depressing drop, but on an adjusted basis, News Corp. made 19 cents per share, which, according to Bloomberg, was a single penny ahead of expectations.

The company's problems with MySpace always make the news these days. Technically, the site is a part of Fox Interactive Media, and it is that division of NWS which took on charges that helped to drive the GAAP loss. Remember when MySpace was so important to shareholder value? Not any more. Facebook and Twitter have now taken all the buzz, and News Corp. just isn't having a fun time with this investment. This is one area that management obviously has to work on.

When News Corp. (NASDAQ: NWS) bought MySpace.com for over $500 million back in 2005, some said it was the way Rupert Murdoch would charge into the digital media audience business in a big way. While that was true at the time, the digital world and its audience can become fickle and change rapidly as new web-based properties develop. It's pretty obvious by now that Facebook has leaped past MySpace and is "the place" to be when it comes to social networking interaction (although Twitter is garnering all the buzz presently).

Why Did MySpace lose its way? MySpace evolved to become a portal, offering music downloads and other goodies, while Facebook kept its social networking status as a place where friends and associates could virtually connect. And there you have it -- MySpace didn't evolve as trends were created and rapidly changed.

In the world of game-changing companies, mistakes and accidents are usually a common thread. Look at MySpace. Initially, the site copied Friendster. But MySpace accidentally forgot about several security features, which allowed users to essentially pimp their profiles. Yes, it was this differentiator that helped propel the site's hyper-growth.

Well, right now the next-big-thing in the tech world is Twitter, which has recently gained the approval of Oprah.

Funny enough, the site came out of a failed venture – called Odeo – and quickly evolved from its initial purpose (that is, a location-based service or group SMS).

Back in the 1990s, I got to meet the folks at Geocities, a site that allowed anyone to create a website. The site was chaotic – but that was the attraction. However, after Yahoo! (Nasdaq: YHOO) bought the company, Geocities drifted into irrelevance.

Well, after the dot-com bust, we saw a new group of creative online platforms emerge. But this time, there was an interesting twist; that is, users could connect with each other. It was an explosive idea, which catapulted some sites into the stratosphere.

Of course, one is MySpace. And, a top writer from the Wall Street Journal, Julia Angwin, has an excellent book on it, Stealing MySpace: The Battle to Control the Most Popular Website in America.

Launched in August 2003, MySpace was the brainchild of Chris DeWolfe and Tom Anderson (the site was almost named "YoPeeps"). Both were part of a struggling dot-com, eUniverse (which was eventually renamed Intermix) and wanted to find the next big idea. And they found it when they ran across Friendster, one of the first social networking sites.

So what to do? It was simple: copy it.
