Eastern tactic (mostly speaking of Japan): create a product for a specific audience, build up a following based on quality of art, story or both but never change the story to pander to a new demographic as you always want a consistent audience

Western: try to make it fit every category in a focus/survey group, if one audience says it's not for them, attack and ridicule them saying it's because they hate another demographic that they won't watch it, story and art design is a last concern after marketing.
