Those services failed because they were trying to sell other people's content, which is a model that had a limited shelf life. Netflix made it work only because they were the first one there, but they are losing all the content owned by the other studios and will have to survive on their own content alone before long. All the new streaming services will succeed because they are attached to major studios, which have proven through decades of success that they generate original content people are willing to pay to see. Basically they aren't "new services" so much as existing studios adding a new outlet to monetize the original content they generate, along with their back catalog. Please tell me why you think Disney or Warner can't support a streaming service, when they own far more content than Netflix? You really believe people are more willing to pay money to watch movies like Bird Box than the movies Disney and Warner Brothers release? Netflix is going to be no different than them, they are basically going to be another studio with the main difference that they don't monetize their content in theaters or on broadcast TV, but only via streaming. Seems to me the players who have more than one way to monetize the same content will be more successful in the long run. Even if its a zero sum game they certainly won't be LESS successful.
