Benefits of ownership. With streaming media increasingly available, you might wonder why you'd want to own a physical copy of movies and TV shows on your Blu-ray Discs and DVDs. Well, you might want to be entertained in a part of the world without Internet access - like when you're watching TV in a remote cabin get-away or keeping the kids entertained while they're in the car. Plus, serious fans of certain TV shows like to own libraries of their favorite movies and shows for marathon watching sessions or loaning to friends.
