National Geographic is looking to help factual fans binge box-set documentaries as part of the launch of a video-on-demand service across Europe. The brand is doubling down on digital with National Geographic+, which will launch in Denmark, Greece and South Africa in 2018.

National Geographic+ will target younger, millennial viewers and feature a curated collection of content across topics including space, Egypt, world cultures, deep-sea exploration and the human body. It will also feature short-form programming and 4K content as well as scripted titles such as Mars, The Long Road Home and Geoffrey Rush’s Genius.

The service will be available on telco Cell C’s Black service in South Africa, OTE’s Greek service Cosmote and Danish pay-TV platform YouSee.

National Geographic+ will take extended non-linear rights to a raft of content with in-season stacking available for some shows. Viewers will be able to stream on up to five devices as well as temporarily download shows.

The service, established by Fox Networks Group Europe & Africa, follows the launch of Fox+ earlier this year in nine territories: Germany, France, Portugal, South Africa, Greece and across the Nordics.

“Consumers are at the heart of our non-linear services; people are used to marathon viewing for scripted, but there hasn’t been a simple and effective way to offer similar experiences within Factual,” said Jan Koeppen, President, Fox Networks Group, Europe & Africa. “At National Geographic, we are passionate about taking our viewers further, to encourage exploration and a better understanding of the world in which we all live. By introducing National Geographic+, we are combining our 129 years of visual storytelling with our rich history of product innovation to ensure that factual stands out in the on-demand world.”
