Los Angeles-based online video content service Revver has picked up Comcast Interactive Capital and Turner Broadcasting as secondary backers in its Series B round of financing.

In its initial round of financing, Revver garnered $2.5 million with an additional $8.7 million added in the Series B round. Comcast and Turner provided an additional $1 million to complete the B round.

The move puts Revver into the company of other Internet sites that have been purchased for formed alliances, such as MySpace.com at News Corp. and YouTube.com’s affiliation with NBC/Universal.

Revver is as one of the few online video companies that split advertising revenue with video creators. The company also tracks the viral success of videos across the Internet.

“The market for online user-generated video content is growing exponentially,” said David Horowitz of Comcast Interactive Capital. “We are excited by Revver’s unique approach in helping content creators create value from their work.”

Turner Broadcasting Vice President Greg Foster added that Turner was eager to use “innovative ways to reach new audiences.”
