Long-running television franchise, “CSI” has a new owner: L.A. entertainment finance firm Content Partners LLC.

Content Partners purchased a 50 percent stake in the franchise from Goldman Sachs in a deal announced Thursday.

The franchise includes “CSI,” “CSI: Miami” and “CSI: NY.” Since debuting in 2000, more than 700 episodes of the shows have been produced, with more to come.

Content Partners was founded in 2006 and buys stakes in entertainment franchises from profit participants such as actors, writers or financial institutions at a discount against future profits. The company has acquired interests in 119 television and film franchises.

The deal is reported to be worth about $400 million. CBS Corp., which distributes CSI, owns the other half of the franchise.

Steven H. Kram, Content Partners chief executive, said the firm was attracted to the deal in part due to the growth of the international marketplace for such programming.

“One of the most attractive aspects of this acquisition is the strong commitment that CBS has made in continuing to aggressively distribute and leverage the ‘CSI’ franchise across all media,” Kram said in a statement.
