Dreamworks Animation projects will be on Hulu, Netflix, Prime as well as linear television. (Hulu gets projects based of Dreamworks properties, Netflix will get shows based off Universal Properties and Original, Amazon will get shows that are specifically commissioned)

(Prime gets USA shows, Netflix gets Syfy shows, Hulu gets combination, and Universal Television comedies are spread between all three with certain being exclusives (Office on Netflix, 30 Rock on Hulu, Forever on Amazon)
NBCUniversal Entertainment Japan on both Funimation and Crunchyroll. (Universal Produced Anime)
