Google CEO Eric Schmidt gave what he just had to know would be a much quoted comment to the Nikkei today, explicitly saying that the company had “begun seriously looking into acquisitions again.”

Music to the beleaguered mergers and acquisitions market, to be sure, especially after a recent uptick from other big companies pulling out their wallets again as the impact of the econalypse subsides.

According to sources, Google (GOOG) is working on at least a half-dozen acquisition deals, most of which are small start-ups in the online advertising and cloud computing arenas.

That would be welcome news for many.

That’s because, as The Wall Street Journal noted in a piece today, “August was shaping up to be the worst month for deal making since 1995, according to data provider Dealogic” (see the chart).

That was, until Disney (DIS) bought Marvel for $4 billion, in a deal announced Monday.

Then yesterday, eBay (EBAY) traded 65 percent of its Skype Internet telephony unit to a group of free-spending private investors, led by Silver Lake Partners, for $1.9 billion.

While eye-popping numbers like that make dealmakers smile, most think it is in the spate of smaller venture-backed companies that more of the action will happen, with big companies like Google, Microsoft (MSFT), Apple (AAPL) and even Yahoo (YHOO) as predators.

Many of these were funded in the Web 2.0 boom and have done well enough, but are figuring out that a link with a larger fish will likely make for a better outcome, along with filling in tech and product gaps at the giants.

Think about Facebook’s $50 million acquisition of social networking site FriendFeed recently and you have the right idea.

According to more than a half-dozen Silicon Valley VCs I have spoken to this week, this is the likeliest kind of exit for a large group of their portfolio companies.

Thus, they are putting on their finest and placing themselves on display in the store window, offering talent and innovation.

“We all realize that a lot of these companies are not going to be independent, so we’re all trying to figure out where they best fit in,” said one VC. “We essentially did business development for a lot of the large companies.”

Thus, here are some companies whose names have been bandied about of late by M&A types who say they are more likely candidates for sale:

Veoh, the Web video portal that MediaMemo wrote about in July, has reportedly been searching for a home for a while now as it struggles in a costly space dominated by giants like YouTube and Hulu.

That goes for many other similar video efforts, such as Joost, Metacafe and Dailymotion, all of which have been trying to gain traction.

There is also likely to be a shakeout in the gaming and “guy” content space, which has also seen a lot of funding in the last several years and less monetary success.

Some possible names here include: Xfire, a gaming instant-messaging company Viacom (VIA) bought a couple years ago for $100 million; Giant Realm, a 20-something guy site funded by Comcast (CMCSA) and others; and UGO, Hearst’s version of a 20-something guy site.

Probably, given the need to focus on monetization, the most active M&A space will be in online advertising.

Sources said Google, for example, has been interested in companies such as Teracent, a dynamic ad-serving and optimization start-up in San Mateo.

There are lots of names in this general arena to pick from, from Tumri to Quantcast to AdMob to the Rubicon Project, not all of which are for sale, but might be for the right price.

Lastly, there is the smart phone and telecom space, where there might be some of the bigger deals.

While Palm (PALM) has been trying mightily to gain traction with its Pre offering, many think that if it does not go as well as hoped, the company will be an acquisition target eventually for giant companies like Nokia (NOK).

While many think Microsoft could also be a buyer of Palm, given the lackluster performance of its Windows Mobile devices, it might be more attuned to a much bigger catch: Research in Motion (RIMM) and its business-oriented BlackBerry empire.

Such a massive acquisition–most of those I bounced that idea off agreed–would be an uphill battle, but it would be perhaps the best fish story ever.

Please see this disclosure related to me and Google.

In an article in yesterday’s Wall Street Journal about an alliance being discussed between Facebook and Nokia, came news about the pair working on a deal to deeply integrate the hot social network with the handsets of the world’s largest maker of mobile phones.

Although BoomTown has seen this movie before–a similar mobile deal with a Nokia (NOK) investment in Facebook was being bandied about a year ago–expect more noise than ever when it comes to social-networking sites and mobile devices in 2009.

As you can see from the chart below, Facebook ran past MySpace in the number of unique visitors via mobile phone in the early fall of 2008 and kept climbing.

Said the Journal article: “In December, Facebook had seven million U.S. mobile users, compared with MySpace’s 5.7 million, according to Nielsen Co.” (Full disclosure: MySpace is owned by News Corp. (NWS), which also owns Dow Jones, the owner of this site.)

And, indeed, to get this kind of traction, Facebook has been very busy ferreting away to get a presence on all the big cellphone makers, so far mostly by building its popular Facebook application for smartphones like the BlackBerry from Research in Motion (RIMM) and iPhone from Apple (AAPL).

Facebook–the Journal piece said–has also been talking to Palm (PALM), which will launch its new Pre smartphone in the spring, and Motorola (MOT), about being integrated into their operating systems too.

The race to be present on mobile devices by everyone and their Internet mother has gotten all hopped up with the introduction of so many smartphones of late, since these devices make any Web app experience much better.

And consumer uptake of these kinds of phones, with big screens and multitouch capabilities, is widely expected to dramatically increase over the next five years,

But here is the dicey money–or nonmoney, actually–quote from the article:

“As with most of the cellphone-software industry, Facebook has yet to find a way to generate meaningful revenue from its mobile services, which include text-messaging features, a mobile Web site and downloadable software. But the number of users accessing its site from phones has grown.”

Oh dear–that roughly translates in Facebook-speak to friending without benefits, with costs rising without much (or any) revenue coming in, to speak of.

Of course, many would argue that both Facebook and MySpace, as well other big players, have to still play hard in the mobile market to gain users–given that consumers are on the move more than ever, digitally-speaking–even if it takes a while to see financial results.

So while efforts by mobile advertising services, such as AdMob, are trying to make that happen and are definitely promising, it’s still a game of growth and not revenue or, of course, profits.

While there are very few bright spots to look at in the start-up space in Silicon Valley these days, especially those relying on online advertising, the San Mateo, Calif.-based AdMob is at least slightly shiny.

The mobile advertising marketplace, backed by Sequoia Capital and Accel Partners, just got a big slug of funding–almost $16 million–to keep pushing to get ads on mobile phones, which has gotten a huge boost from the popularity of the iPhone.

The number of ads AdMob is serving on the iPhone jumped to more than 100 million in September, compared to 35 million the month before, for example.

The massive data usage by users of the popular mobile device by Apple (AAPL) has clearly turbocharged AdMob’s prospects, which were already on the rise. Compared to a year ago, the company said, the number of ads it served more than tripled the number of ads served on a monthly basis to 4.5 billion.

Obviously, the better quality and more actionable nature of ads on improved screens is the reason for the shift, which should accelerate as more smartphones like Google’s G1 and newest Blackberry Storm from RIM (RIMM) become more popular too.

Most importantly, even now, AdMob is cash flow-positive, which is not a bad thing to be in the current econalypse. It also has a cushion of cash–AdMob had previously garnered $15 million in funding from Sequoia and Accel.

It’s not all sunshine and daisies, of course, since the ad market in general is headed for a deep slump, and new markets are not going to grow as quickly, as marketers pull back from spending.

But, when the economy turns, the mobile advertising market is clearly going to be a fast-growing arena, with big players like Google (GOOG), Yahoo (YHOO), Nokia (NOK) and Microsoft (MSFT) as AdMob competitors (or potential acquirers, especially Google).

With the money it just raised, AdMob said it would be getting ready for that race, and also use it to expand internationally.

Here’s my video interview with Omar Hamoui, Founder and CEO of AdMob, on all that and more, as well as a tour of its offices:
