According to sources close to the situation, Wal-Mart Stores paid just over $300 million in cash for Kosmix.

The six-year-old Mountain View, Calif.-based company–which has built a social media platform that organizes content by topic–has raised $55 million from a large group of Silicon Valley venture firms.

The acquisition by the Bentonville, Arkansas-based retail giant was announced earlier today.

Wal-Mart did not disclose terms of the deal, which is focused on building out its social and mobile e-commerce offerings.

The price for Kosmix is a pricey one to do so, but traditional retailers need to jump into the digital market now dominated by app-happy, smartphone-wielding customers.

Kosmix will join the newly formed @WalmartLabs, the company said.

Kosmix was founded by the team that sold pioneering e-commerce company Junglee to Amazon in 1998.

After that, Venky Harinarayan and Anand Rajaraman raised $55 million in funding from Time Warner Investments, Accel Partners, Lightspeed Venture Partners, DAG Ventures, Bezos Expeditions, and angel investors Jon Miller and Ed Zander.

As eMoney’s Tricia Duryee wrote earlier today:

The company may be best known for powering TweetBeat, which it defines as a real-time social media filter for live events. It also operates Kosmix.com, where people go to discover social content by topic, and it operates RightHealth, which it claims to be one of the top three health and medical information sites by reach.

One interesting aspect of the deal: Accel’s senior partner Jim Breyer–who was not the principal VC in the Kosmix investment–is on the board of Wal-Mart. Presumably, he recused himself from the decision.

The company did not disclose terms of the agreement, but said the acquisition would be instrumental in building out both its social and mobile initiatives.

Kosmix will join the newly formed @WalmartLabs and continue to be based in Silicon Valley, the company said.

Wal-mart said the @WalmartLabs team will work on building out its social and mobile commerce strategy to link together its bricks and mortar stores with e-commerce. Today, Wal-mart operates physical stores in 15 countries and e-commerce businesses in nine countries.

Kosmix was founded by Venky Harinarayan and Anand Rajaraman, who sold their first company, Junglee, to Amazon.com in 1998.

The six-year-old company Kosmix has raised $55 million in funding from Time Warner Investments, Accel Partners, Lightspeed Venture Partners, Dag Ventures, Bezos Expeditions, Jon Miller, and Ed Zander.

In explaining what the company does on its Web site, it writes: “On any given day, people share 830 million items on Facebook, upload 6.1 million photos to Flickr, add 2.1 million minutes of video to YouTube and send 65 million tweets. Kosmix cuts through this noise to find content that matters to you.”

It’s not particularly clear how Kosmix leads to better mobile and social interactions. The company may be best known for powering TweetBeat, which it defines as a real-time social media filter for live events. It also operates Kosmix.com, where people go to discover social content by topic, and it operates RightHealth, which it claims to be one of the top three health and medical information sites by reach.

The transaction is subject to the customary closing conditions; the company anticipates it will close during the first half of this year.

“Larry Ellison: We’re a big fan of open source–in fact, we’ve had the major transaction engine to MySQL–it’s something Oracle bought years ago and has invested in it to a higher level than it was invested in before. We believe in open source, we’re a huge supporter of Linux. MySQL and Oracle do not compete–at all….There’s a long list of database machines and database software we compete against–we never compete against MySQL. They’re both called databases, they address very different markets–furthermore, it’s open source.

Ed Zander: If they ask you to spin it off, will you?

LE: No.

EZ: If they told you to spin it off, would you?

LE: No. We’re not gonna spin it off. The U.S. government cleared this, we think the Europeans are gonna clear this, and we are not going to spin anything off.”

– Excerpt from Oracle CEO Larry Ellison’s September Churchill Club interview with former Sun CEO Ed Zander

Looks like Oracle has managed to ease European regulators’ antitrust concerns over its $7 billion acquisition of Sun–perhaps even enough for them to approve the thing.

This morning, Oracle (ORCL) and the European Commission both said they have had “constructive discussions” about the company’s plans for Sun (JAVA) and more specifically, its open-source MySQL database software.

Driving those discussions: A 10-point list of commitments from Oracle intended to ensure that MySQL will remain a competitive force in the database market. In the list, Oracle spells out plans for the database software, promising to boost spending on research and development, refrain from seeking commercial licenses from makers of MySQL storage engines and to establish a customer advisory board of MySQL users.

These concessions went over well with the EC, which is clearly warming to the idea of a Sun-Oracle union. “Today’s announcement by Oracle of a series of undertakings to customers, developers and users of MySQL is an important new element to be taken into account in the ongoing proceedings,” said the EC in its statement.

“In particular,” the EC continued, “Oracle’s binding contractual undertakings to storage engine vendors regarding copyright non-assertion and the extension over a period of up to 5 years of the terms and conditions of existing commercial licenses are significant new facts.”

European Union regulators have until late January to make their decision.

“It was a tough decision because I love the job,” said Zander. “I will be 61 in January and it is time to make way for one of the younger guys.” Sure is. With Motorola’s global market share slipping into the mud–it now ranks No. 3 after Nokia and Samsung with around a 13% share, down from about 21% just a year ago–the company is in desperate need of a turnaround.

Whether Brown’s the guy to do it remains to be seen. Certainly, investors aren’t so sure. “There are some investors who are disappointed that they didn’t bring in somebody from the outside,” Kaufman Brothers analyst Raimundo Archibold told Bloomberg. “This would have been an opportunity to bring in some fresh blood.”

Joan Lappin, president of Gramercy Capital Management, agreed. “I don’t see him as a person who is going to come in and razzle-dazzle the troops,” she said. “He’s kind of a bland guy.”

While Jackson runs a small operation, he uses his Web site, YouTube videos, posting to wikis and other online tools in his effort to build a small group of disgruntled investors and offer a “Plan B.”

Zander, who appeared at our D3 conference, might want to be careful. Jackson craftily asked Semel at the Yahoo meeting–see my post on it here and the video from it below–whether he had the “fire in the belly” to continue as CEO at the troubled Internet giant. At the meeting, Semel answered with a hearty yes, but was gone soon after.

As of yesterday, Jackson now has a lot more fodder in his fight with the telecommunications-equipment maker, when Motorola warned of weak shipments of cellphones and said its mobile-devices division would lose money for the year.

With the stock in the tank, management turmoil, a lackluster product line and rumors of a Zander exit, let us not forget the recent explosive launch of the iPhone to cause even more agita at the company.

But let Jackson take it from here with his recent video on Motorola, followed by mine from the Yahoo board meeting in June:
