Discovery Digital Networks, the digital arm of Discovery Communications, has tapped Nathan Brown as senior VP of development and operations as it gears up for the relaunch of millennial-targeted online network Seeker.

Most recently, Brown was senior VP and G.M. of video at AOL’s Huffington Post overseeing all areas of global video, TV and film. At Discovery Digital Networks, he will guide business strategy and audience growth and have operational responsibilities. Brown will be based in Discovery’s San Francisco office.

“Nathan is a strong, innovative executive with an intimate knowledge of digital audiences and a proven track record of growing digital businesses,” said Suzanne Kolb, executive VP and G.M. of Discovery Digital Networks, to whom Brown reports.

Kolb, who joined Discovery in January, was previously president of NBCUniversal’s E! Entertainment.

Prior to HuffPost, Brown was G.M. of video and TV at Complex Media, which Verizon and Hearst announced they will jointly acquire. Earlier in his career, Brown co-founded Rehab Media, a film company producing short- and long-form videos, branded entertainment, commercials, music videos and documentaries.

Discovery Digital Networks, whose properties generate more than 300 million monthly video streams across platforms, later this year plans to a revamped version of Seeker, with 250-plus videos premiering each month across multiple digital platforms, including on a redesigned version of Seeker.com launching in May.

The division’s channels and shows include Discovery VR with virtual-reality programming, SourceFed, “The Philip DeFranco Show,” DNews, “Rituals” with Laura Ling, and sketch-comedy channel Nuclear Family.
