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.

Do you remember before computers churchgoers got up, got dressed and walked or drove to their local church for a live performance by Pastor XYZ, prayed as a congregation, received the Pastor's in person blessing and returned home?

With the advent of computers, the world has changed. People use computers to shop online, get their news, express their opinions and search the world for information about almost anything we can imagine.

Now churches are using the computer to provide church services with all of the components of a regular church service, expect for person to person interaction. These sites are interactive and even provide music as well as live pod casts.

Company attitudes toward social media sites vary. Some swing the doors wide open, allowing employees to tend to their Facebook farms and update Twitter statuses throughout the day. Others lock 'em down, keeping non-business site access to a minimum.

A recent study found that, in the United States, 77% of employees with Facebook accounts check in with the community from the office. And, the amount of time they're spending in this part of the online world is growing. In the United Kingdom, another study found that 57% log in regularly from work, costing their employers 40 minutes a day.

Philip Wicks, a consultant at Morse PLC, a technology research firm in London, "It isn't just something you can do for half an hour during a lunch break but all through the day and because of that, it has a huge impact because people aren't necessarily concentrating on what they should be doing during the day." He estimates that this translates to lost productivity of $2.25 billion a year.

It seems like the obvious move would be to block the sites, but William Beers of PricewaterhouseCoopers disagrees. "Instead of trying to shut it down, I think we should try to embrace these technologies, put in a nice policy that governs it and explain to users the risks related to it, provide some training and then see what business benefits we can have from it," he said.

Vibe, the urban music magazine, is clawing its way back to life. New owners and editors are trying to make the magazine a success reality again, and they are making the web a priority ... which shouldn't be news but is for an ailing print industry.

The new editor-in-chief, Jermaine Hall, told AdAge that "Vibe.com is really the hub," and that everything needs to point back to the online presence. The print publication will be just one part of the Vibe Lifestyle Network, a move we're also seeing with the likes of Rolling Stone, where the website is being brought back into the fold (and may actually get some resources).

Once upon a time, retailers measured success by the number of people walking by in the mall, how many entered the store, the percentage they spent, and basket size. Now, a world of zeroes and ones has changed their perspective entirely. Social media is expected to be the star during the coming holiday season, with retailers pushing Facebook, YouTube, and Twitter content to get in front of consumers and affect either online or in-store purchases. Smaller Christmas budgets are expected, so the fight is on to garner as large a share as possible of a shrinking pie.

Of course, nobody would come out and say, "Social media is nonsense, and I'm not getting anything for my investment." So, when the likes of Starbucks (NASDAQ: SBUX), JCPenney (NYSE: JCP), and Target (NYSE: TGT) say that social media is connecting them with their customers and leading to more effective campaigns and product launches, do take it with a grain of salt. What can't be ignored, however, is that they're committing more resources to social media marketing, even though it's still far too soon to tell if it will be effective.

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.

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.

One known consequence of the spread of the H1N1 flu? Possible, short-term school closures, as well as keeping under-the-weather kids out of school, to help contain the virus.

One little-known consequence? Traffic jams on the Internet, caused by all those school kids and adults out sick from work, logging on to the Web from home -- something that could overwhelm Internet networks, a Government Accountability Office study warns, and The Washington Post reported.

Unless you already have a major foothold in the search engine market – or an amazing, disruptive technology that can make the world take notice – there isn't much point in staying. Competing with Google (NASDAQ: GOOG) is hard enough, even when you're Yahoo (NASDAQ: YHOO) or Microsoft (NASDAQ: MSFT) ... and, apparently, when you're IAC/InterActive Corp (NASDAQ: IACI). Barry Diller is ready to give up Jeeves, but only if asked nicely.

Diller's presence in the search space is Ask.com, ranked #4 behind Google, Yahoo and Microsoft's Bing. With a substantial gap between first and second, fourth barely registers at all. Ask.com has only a 2% U.S. market share, according to Hitwise, more than 60 percentage points behind the industry leader.

Baidu (NASDAQ: BIDU), China's leading search engine, sold off during Monday's after-hours session after the earnings report for the third quarter was issued. When you're a theoretical growth company like Baidu, missing estimates on the guidance side is never a good thing to do.

Nevertheless, Baidu delivered in Q3 itself. Sales skyrocketed 39%. Net income per share exploded over 40% to the upside, coming in at $2.07 per share on a GAAP basis. Adjusting for items, the company earned $2.16 per share. Earnings.com gives an expectation of $1.81 for per-share profit.

Traditional retailers haven't exactly embraced online sales channels. Sure, they all have websites, and they sell varying amounts of merchandise through them, but they've been slow to tap into the potential. When I was watching the space as an analyst at a major consulting firm (admittedly, back in 2007), many retailers equated a website to a new store opening. Finally, however, this industry is starting to see the potential of this venue, particularly when it comes to tracking consumer behavior.

When the CEO of Macy's (NYSE: M), Terry Lundgren, says that online sales are only good for 6% of last year's total sales, it's a hint. The translation: "We focus on where the revenue is" is much different from "We focus on where the revenue could be." Aeropostale (NYSE: ARO), on the other hand, sees the upside of playing in the online space, which is where it saw revenues spike 85% last year. Aeropostale has seen increases in traditional venues too, but nothing like what it's realized on the web.

So, maybe there's something to this internet, after all.

It's tough to take on Google (NASDAQ: GOOG). The search engine behemoth owns 65% of the U.S. search market and has a commanding brand presence. Yet, the software maker up the coast isn't known to give up easily. Microsoft (NASDAQ: MSFT) has cut a deal with microblogging site Twitter that should give it an edge in the battle to harness data and make it easier to find. A new deal will feed all those tweets into Bing, the Microsoft search engine.

Twitter is giving Microsoft full access to its data, in a deal announced Wednesday. Bing will provide search functionality for Twitter that you won't find in Google, which seems to have been outbid for the rights to the "tweet-stream." Under the deal, Bing will be able to index and display the tweets almost immediately as they are posted.

Online auction giant eBay (NASDAQ: EBAY), a business that counts Amazon (NASDAQ: AMZN) and Yahoo! (NASDAQ: YHOO) as related companies, was not popular in Wednesday's after-hours session. The third-quarter report just didn't do it for Wall Street, so Wall Street decided to make some trouble and bring the per-share price of the stock down by 4.5%. Oh sure, the company beat earnings by the most famous amount there is -- the proverbial penny -- but, according to this Bloomberg piece, guidance was not so inspiring.

The top line was actually pretty cool. Net sales saw an increase of 6%. Unfortunately, the bottom line couldn't take advantage of such growth. On an adjusted basis, net income dropped 16% to 38 cents per diluted share. And, as I just said, that was one penny ahead of the analysts.

The number two search engine in the United States turned in a fantastic third quarter, far ahead of expectations. Cost-cutting, layoffs and business divestitures led to a surge in Yahoo's (NASDAQ: YHOO) profits and a 4.8% increase in share price in extended trading on Tuesday evening. Net income more than tripled to $186.1 million (13 cents per share) from the third quarter of 2008's result of $54.3 million (4 cents a share). Sales (exclusive of fees passed to partner sites) reached $1.13 billion, slightly above the $1.12 billion expected by analysts, according to a Bloomberg survey.

With the advertising market in rough shape and competition from Google (NASDAQ: GOOG) continually rising, Yahoo refocused on its core properties: the home page, messaging and mobile services. The company trimmed what it didn't need, which is why it was able to boost its earnings even with a decline in revenue. Increased ad revenue from auto manufacturers, travel companies and consumer product manufacturers also helped.

Yahoo's chief financial officer, Timothy Morse, says that the company's markets are "starting to stabilize." Of course, Yahoo itself must be doing something right: its share price is up 41% this year.
