Motorola Mobility has bought two-year-old video discovery start-up SetJam for an undisclosed sum.

SetJam CEO Ryan Janssen wrote of the acquisition in an e-mail cited by VentureBeat: "I'm writing to let you know that today SetJam was acquired by Motorola Mobility. We are all very excited about this transition here at SetJam. Motorola and SetJam share the vision of making content delivery, discovery, and consumption seamless across any screen, and as a world leader in video technology, Motorola will provide us with unprecedented levels of reach and distribution."

Janssen, the former chief operating officer of online financial toolbuilder Angelsoft.net, founded SetJam in June 2009. Originally it aimed to be the TV Guide of the Internet, competing with companies such as Clicker and SideReel as it attempted to become the premier curator of videos online.

The odds were against SetJam from the start: It launched at the same time as Clicker.com, which had $8 million in venture capital funding compared to SetJam's $50,000. (As Janssen wrote at the time: "the URL of the start-up,  'clicker.com,' probably cost more than the life savings I'd put into SetJam.") To date, the company has raised less than $1 million.

SetJam's products also include Web widgets that let businesses give customers an easy way to buy videos online. The company has an XML Download, which downloads its entire entertainment database to a user's computer. And–probably of most interest to Motorola–SetJam has recommendation and personalization technology that can be used in connected devices such as Motorola set-top boxes.

The technology could eventually make its way to Google–the online search giant is in the process of buying Motorola Mobility. The $12.5 billion acquisition still is under regulatory review.
