National Geographic+ will take extended non-linear rights to a raft of content with in-season stacking for some show.

"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," says Jan Koeppen, FOX Networks Group Europe & Africa president in a statement announcing National Geographic+ as the latest digital extension.

"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".
