Digital-media company Fullscreen has appointed Jason Klarman, formerly a senior exec at NBCUniversal’s Oxygen Media and Bravo Media, its first chief marketing officer.

Klarman will lead strategy for Fullscreen’s overall brand, integrated marketing business and original programming. He reports to George Strompolos, Fullscreen’s founder and CEO.

“Jason has a track record of connecting brands with passionate audiences who push the culture forward,” Strompolos said. “He’s defined brands at the forefront of the media business, and as Fullscreen evolves into a consumer-facing media company, there’s no one more qualified at the helm.”

Klarman most recently was president of Hashtag Media Ideas, a consulting firm specializing in marketing and content strategies for digital-media businesses. He was president of Oxygen from 2008 to 2013, where he led the re-launch of the network targeted at 18-34 female audiences overseeing such shows as “The Glee Project,” “Tori & Dean: Home Sweet Hollywood,” “Best Ink” and “Preachers of LA.”

Prior to Oxygen, Klarman was executive VP of marketing and digital at Bravo Media, which rebranded in 2005 with the “Watch What Happens” tagline. Before joining Bravo in 2004, Klarman was senior VP of marketing for pop-culture and arts network Trio. Earlier in his career, he was VP of marketing at Fox News Channel and helped launch the cable news network.

Fullscreen runs one of the largest YouTube multichannel networks, reaching over 600 million subscribers with 5 billion video views per month. The Culver City, Calif.-based company is owned by Otter Media, a joint venture of AT&T and Chernin Group.

Fullscreen recently announced plans to launch a subscription video-on-demand service, and earlier this year expanded into producing feature films and series, including “The Outfield,” starring Nash Grier and Cameron Dallas and Legendary Digital Media’s “Electra Woman and Dyna Girl,” starring Grace Helbig and Hannah Hart.

“Fullscreen is transforming the way content is created, consumed and monetized,” Klarman said in a statement. “I couldn’t be more excited to join the team as it navigates this incredibly exciting, transformative time in the media business.”

Klarman holds a bachelor’s degree in economics and political science from the U. of Michigan and an MBA in finance and marketing from New York U.
