Kirkland, Wash.-based 1Cast, a mobile and online streaming video service, said it is coming out of beta today and that it has secured new partnerships with Clearwire (NSDQ: CLWR) to run over its WiMax network and with Boxee to be available in living rooms. Release.

1Cast allows people to search videos for subjects they are interested in, such as “Balloon Boy” or “Michael Jackson,” and then set up tailored newscasts. Currently, the service works online, and is available on both iPhones and Android phones. Today, marks the company’s expansion into the living room and on to WiMax networks in addition to coming out of beta. Anthony Bontrager, 1Cast’s President said they are delivering 3.2 million streams a month and 4.2 million ad impressions. On the web, people watch for an average of 12 to 15 minutes, while on the mobile phone, people are averaging even more—36 minutes per session.

Bontrager said they launched in beta on the web and on the iPhone in November, and then on Android in February. “For us, it’s about touching users wherever they are, not everyone is in front of desktop, just like they aren’t always looking at their phone. Mobile is a huge piece of that.”

It’s perhaps not a surprise that 1Cast was able to secure a deal with Clearwire. Not only are both companies located in the same suburb of Seattle, but they also have the same backers. 1Cast has raised an undisclosed amount of money from Craig McCaw’s investment arm Eagle River. The wireless mogul also founded Clearwire. Bontrager: “It didn’t hurt in terms of getting in front of the right people, but we had to go through an exhaustive process. There was no guarantee.”

Bontrager said they believe in the ad-supported and freemium models. Right now the service is being completely funded by advertising, but they expect to launch a paid application in 2010 that will have different content. Today, 1Cast’s content partners include most major global broadcast news stations, such as BBC World News, CNBC, Bloomberg, Fox Business News, Reuters, Dow Jones (NYSE: NWS), AFP and others. Bontrager said that the content owners are interested in participating because when a user searches the videos, the competition is stacked up against each other. “This is a good thing for them. News is perishable, and now they have extended monetization and a three screen environment,” he said.
