Video entertainment network Machinima announced Tuesday an $18 million in financing led by Warner Bros. Entertainment. The investment by the Burbank studio builds on an existing partnership with Machinima, in Los Angeles, which has distributed two seasons of “Mortal Kombat: Legacy,” a live-action Web series produced by Warner Bros. Digital Distribution. Contributing to the financing are existing investors MK Capital in Santa Monica, Redpoint Ventures in Los Angeles and Google Capital in Mountain View. Machinima started in 2000 as a website to promote the creation of animated videos in virtual world environments and later expanded into an online multi-channel network. The company works with thousands of channel partners and is a premium brand that reaches millions of daily users, said Thomas Gewecke, chief digital officer and executive vice president, strategy and business development, Warner Bros. Entertainment. “We’ve been impressed with Machinima as a distribution partner, and by their focus on creators and commitment to high quality, exciting original digital content,” Gewecke said in a prepared statement.
