This means you can still watch channels including: Animal Planet, Discovery HD, Discovery History, Discovery Home & Health, Discovery Science, Discovery Shed, Discovery Turbo, DMAX, Eurosport1, Eurosport2, Investigation Discovery, TLC and Quest.

We are also delighted to announce a new deal with PBS America that will bring the best of PBS's factual programming to Sky, covering history, science, current affairs, arts and culture. We are adding over 1,000 hours of programming to our On Demand service from channels like History and National Geographic. This means ours customers can enjoy the very best factual programming available.
