All of them. Seriously, the idea of a "fan base" is stupid. People shouldn't identify themselves by what they like. If you like a show, watch it. Hell, talk to it about it to others that also like it. Once you start giving yourself a *title* based on that interest its gone too far. There is no "fandom" for shows like Breaking Bad or Game of Thrones, they just have large followings. Probobly because their target age group is generally 18+ and its the teenagers who typically resort to creating things like "whovian" or "sherlockian".
