Google (GOOG) is accustomed to being in the top spot. It leads search and virtually owns the online ad space. Its Google News portal is among the top sites for directing traffic to media outlets. But, the behemoth is starting to feel the feet from social media sensation Facebook.

Not only is the rather young platform stealing market share from Google News, it's now encroaching on its e-mail turf ... a situation that Google isn't taking lightly. To compete more effectively with Facebook, Google is upgrading its Gmail capabilities to include more social media tools reminiscent of those found on its competitor.

Facebook wants to take over the display advertising on its larger-than-life social network. In the process, it will stop using Microsoft (MSFT) to display the majority of advertising at what is becoming one of the most heavily-trafficked pieces of Internet real estate globally.

Is Microsoft angry? It should be -- every time the world's largest software company crafts some small way to try and compete with Internet advertising leader Google (GOOG), the rugs gets pulled from under it.

How are readers finding the news? Well, increasingly, the answer is Facebook. The social networking site, which boasts well over 350 million registered users, is now the fourth largest referral source of traffic to online news destinations. Almost a year ago, only 0.5% of traffic to news and media sites came from Facebook. Today, that level is 3.5%, according to data from Web analytics firm Experian Hitwise.

Only Google (GOOG), Yahoo! (YHOO) and MSN (MSFT) send more traffic to news sites. Google News, a subset of the search engine giant, failed to keep pace with Facebook, despite the fact that it exists specifically to send Internet users to media outlets. Only 1.39% of referrals came from this source.

It seems kind of strange, but the market for virtual goods has become red-hot. Basically, these are nothing more than digital footprints, such as cool graphics used as gifts on a social network or even weapons in online games.

So how big is this market? According to Atul Bagga, an analyst at ThinkEquity, the market is expected to double this year to $1.6 billion. And by 2012, the market may reach $3.6 billion.

The three major social media sites have been pushing new tools out to their user communities aggressively over the past year. Each company has its own set of rumors, from IPOs to being on both sides of an acquisition. While the ultimate 2010 aims of Facebook, Twitter and LinkedIn may not have been revealed to us yet, it is clear that all three are looking for ways to beef up revenue and demonstrate long-term viability.

Whether or not Facebook goes public this year, it's still pointed toward that ultimate goal. The 350-million member social network is focused on finding new sources of revenue and gaining better penetration into those it already has. Even if it's more than a year away, it's never too soon to start shoring up your financial statements for an IPO. The latest new feature from Facebook, which has been announcing enhancements fairly rapidly over the past few months, is targeted directly at advertisers, underscoring the importance that the company's attaching to revenue growth.

It looks like 2010 will be a strong year for IPOs, especially for tech offerings. Of course, one of the most highly-anticipated deals is Facebook. No doubt, it would give the market a big jolt.

But sadly, it looks like we may have to wait. At a conference in Munich, Facebook's two largest investors -- Jim Breyer of Accel Partners and Yuri Milner of Digital Sky Technologies (DST) -- said "no" to an IPO in 2010.

The Twitter-verse continues to get interesting. I've always felt that the returns are to be found around Twitter rather than with Twitter itself, and the venture capital community seems to be acting from the same position. Twitter interaction platform HootSuite just announced a new round of venture capital funding, with $1.9 million in fresh money coming in the door to support its growth efforts.

HootSuite, which was started by Invoke Media in November 2008, has evolved into a brand monitoring, file-sharing and social media integration utility. Only a year later, it has attracted more than 300,000 users, from Time (TWX) to Martha Stewart to the White House to Aol (AOL).BloggingStocks is among the Aol blogs using HootSuite.

Looking back on what became a tough end to a tough year for the retail sector, the one bright spot was the online sector. Shoppers whipped out their plastic at a record rate on Black Friday, a trend that continued throughout the season.

The Amazon (AMZN) Kindle killed the competition, reinforcing the status of the online channel as the future of the retail business. Social media, in particular, had its first real test this year, as many companies -- including Best Buy (BBY), JCPenney (JCP) and Target (TGT) -- used the likes of Twitter and Facebook to engage customers, publicize sales and generally increase revenue. The next stage in the evolution, of course, is to use shopping behavior to trigger viral results.

If Mark Zuckerberg knew then what he knows now ... Facebook would be more like MySpace, which is now owned by News Corp. (NWS). And, he's willing to admit this in public.

In a six-minute on-stage interview with TechCrunch, Zuckerberg went on at length about the social media platform's privacy settings, which have been the subject of unending debate. He says that he'd make more data public by default if he could start Facebook again. Though Zuckerberg cites Internet trends that indicate a reduced concern with privacy, the real reasons are more likely financial.

The New York Times (NYT) is putting its 2.3 million followers to work. It isn't ready to start charging a la carte for Twitter advertising, but it is including the channel in the comprehensive packages it presents to advertisers. And, the Times isn't alone. Several media outlets (including BloggingStocks) have ads running through their Twitter streams, but this is still virgin territory, for the most part, and media companies are still feeling their ways through it.

Facebook could use more older women, not to mention younger people in general. As the company pushes toward what is expected to be an IPO in 2010, it needs to shore up its user base in all demographics, if for no other reason than to diversify against a new social media platform that appeals to a specific community. So, even with the site pushing past 100 million monthly active users according to its advertising tool, with the addition of 5 million in December, there is work to be done if Facebook will make a successful entry into the public market.

Long derided by "serious folk" as a place for kids, Facebook's membership consists mostly of adults. Fifty-six percent of the user base is female, and 60% of users are 25 years of age or above. In fact, 20% of them are at least 45 years old. Some of the groups that are underrepresented are showing rapid growth. Men over 55 grew twice as fast as their female counterparts, though the younger generation moved onto Facebook most aggressively last year. Users age 26 to 34 showed the biggest overall increase in 2009, with 839,000 monthly active users. This represents a substantial shift from the trend earlier in the year, in which it was the later generation flocking to Facebook. Women over 55 didn't jump on the bandwagon as quickly as other groups.

Look, 2009 was a "flush" year. Market rallies were constrained by the low baseline set at the end of 2008, unemployment was high and caution defined nearly every corporate decision. The travel market sucked. The art market sucked. The financial industry labored on with the support of taxpayer money while 140 banks were forced to call it quits. So, we turn to the new year, as yet undefined, for excitement of the type we want ... and it seems likely to deliver. As Nero played from the rooftops, the social media industry inched forward to the climax we hope to see this year -- the initial public offering.

The action hasn't really begun, and the signals emitted are open to various interpretations. Nonetheless, Facebook's new dual-class stock structure is hard to miss, as it would protect the influence of early entrants to the company -- either as investors or options-compensated employees in the event that the 350 million-strong social networking site brings ownership opportunities to the public.

Facebook was busy on Christmas Eve and Christmas Day, according to Hitwise, but people weren't playing online games. It seems they were more focused on staying in touch and spreading the usual holiday cheer than tending to their farms, cafes and organized crime battles.

Over the holidays, Facebook was the top Website visited in the U.S., Hitwise reported via its Twitter account. The Web metrics company tweeted the bold statement: "Facebook was the most visited site in the US on Christmas Eve and Christmas Day. 1st time the site has been the #1 visited US site ever."

Revenue hasn't been as fast to change as end-user sentiment, but all that looks like it's coming to an end next year. Social networking site Facebook, which passed 350 million users last month, is poised to move ahead of rival MySpace in ad revenue in 2010, according to a report from eMarketer. The research firm expects Facebook to rake in $605 million in ad spend next year, compared to $385 million for MySpace, which is a News Corp. (NWS) property.

According to Debra Aho Williamson, senior analyst at eMarketer and author of Social Network Ad Spending: 2010 Outlook, "As more marketers incorporate social networks in their business, they will no longer look at them as siloed destinations. Instead, they will look to increase the impact of their social network presence by linking it to other marketing initiatives, both online and offline."

The Walt Disney Company (DIS) has a high-caliber board of directors, which includes heavyweights like Apple, Inc.'s (AAPL) Steve Jobs. Having solid leadership has been critical for the company's growth, which is not easy when dealing with the whims of kids.

So, this week Disney added another top operator to its board: the COO of Facebook, Sheryl Sandberg. While she has held the post since only March 2008, her Internet savvy is much deeper. For example, she managed the highly successful AdWords and AdSense programs at Google Inc. (GOOG).
