Now that all of the major search engines have acquired interactive marketing specialists, the next wave of buyouts may come on the content side. Of course! Once your online advertising possibilities expand, it makes sense to broaden the Internet traffic you control.

So it probably wasn't much of a surprise to see England's Telegraph report over the weekend that Yahoo! (NASDAQ:YHOO) may be making a $1 billion play for the Bebo social networking site.

Bebo is no MySpace. News Corp.'s (NYSE:NWS) site is the crown prince of social networking, complete with a jaw-dropping 179 million registered users. However, Bebo is no slouch. The site has more than 31 million members and serves up more than 5 billion page views a month.

The fast-growing site knows how to draw a crowd. Apparently, it's also drawn a fair share of suitors, if one is to believe Telegraph's rumor-mill claims that Bebo spurned offers from British Telecom (NYSE:BT) and Viacom (NYSE:VIA) last year.

Oooh, Bebo I love your ways
So why is Yahoo! supposedly willing to pay twice as much for Bebo as News Corp. paid for market leader MySpace in 2005? To be fair, MySpace was a smaller phenom when Rupert Murdoch's company bought in two summers ago. Its parent company Intermix was generating just 27 million monthly visitors across its sites, with most of those users logging into MySpace. Bebo stacks up nicely, and social networking is no longer a fringe dot-com niche.

Social networking is also seen as an easier advertising sell these days. Big brands are no longer afraid of promoting products on youth magnet websites. If that's where the impressionable audiences are hanging out, that's where the ad impressions have to be.

Only a year after News Corp. paid $580 million for MySpace, Google (NASDAQ:GOOG) offered to pay News Corp. $900 million for the right to fill the site's online advertising and paid-search needs over the next three years.

Sure, Bebo is young. The site was launched just a few months before MySpace got hitched. However, the site would fit well into the Yahoo! portfolio of acquired properties. Like Flickr, Bebo was founded by a charismatic husband-and-wife team. Like both Flickr and social bookmarking site, Bebo's DNA is all about the Web 2.0 power of building passionate communities.

Bebo fits. Yahoo! has the money. It has to be encouraging to any potential Yahoo! acquisition to see the welcome autonomy that the search engine giant has granted many of its buyouts. So when does Bebo sign on the dotted line?

Hold your horses, compadre. A rumor is often little more than wishful thinking.

Making it happen
If Bebo has in fact turned down other offers, it has little reason to fall blindly into Yahoo!'s arms. Obviously, MySpace would be worth far more today as a stand-alone entity than it was when it handed over the keys two years ago.

However, you never know when a site's popularity has peaked. The dot-com graveyard is lined with upstarts that were too greedy for their own good. Social networking is a niche with a thin moat, and the landscape will only get more crowded in the future.

Bebo may be seen as a site with plenty of upside potential, but it's already pretty popular in places like England and Ireland. That's how it goes with social networking. Google's Orkut is typically seen as a social networking bust stateside, but it's huge in Brazil.

If Bebo balks or demands too much, Yahoo! can always see if Facebook is any humbler these days. That would be fine for Bebo if Bebo in 2007 is like MySpace in 2005, but what if it's more like Friendster in 2003?

These are intriguing times. After the recent wave of high-profile digital marketing acquisitions, I can definitely see Internet content as the next feast worth unhinging the jaws for.

I have recommended popular dot-com hubs like CNET Networks (NASDAQ:CNET) and The Knot (NASDAQ:KNOT) to Rule Breakers subscribers on their merits as stand-alone companies, but the climate is certainly ripe for them to be fresh buyout fodder once the major search portals have a chance to work up their acquisitive appetites again.

In another article today, I argue that the digital marketing bandwagon is full. The next to leave town appear to be companies that command healthy amounts of Web-based real estate.

Pack your bags, Bebo. There's a deal to be had out there, somewhere.
