XiveTV, an Internet-based network focused on documentaries of all kinds, launched today on YouTube and Hulu as well as on apps for the iOS and Android mobile platforms. The site was founded by Greg Diefenbach and Thomas Lucas as part of Alliant Content LLC.

XiveTV_ThomasLucas_HeadshotThe company bills itself as “smart entertainment for the passionate and curious,” and offers a searchable library of more than 2,000 hours of long-form documentaries in areas such as history, science, space, wildlife and adventure, including notable previously-aired series such as Cosmic JourneysTornado Chasers, Psychic Investigators and Austin Stevens Adventures. It will be ad-supported with an option to sign up for ad-free subscriptions.

XiveTV features its own original content plus shows from more than 20 major media organizations, including ITV, Sky Vision, Digital Rights Group and Cineflix. The new service also will include Alliant Content’s existing series such as Pure History and Space Rip, as well as its existing 500,000-person subscriber base streaming more than 20 million minutes of programming weekly. The company has offices in New York and Washington, D.C.

The company says its viewers watch an average of two-thirds of its long-form shows, an average that jumps past 90 percent for the most poplar programming. That’s a big difference from the typical Short Attention Span Theater that has characterized most online video consumption.

XiveTV won’t be alone in the online doc space for long. The Discovery Channel’s founder, John Hendricks, has announced his own similar effort, CuriosityStream, launching next month.
