Category:Cultural references from the real world

 contains articles about literary works, television shows, films, music, fictional characters, food, and other elements of real life popular culture which are mentioned or referred to in the Doctor Who universe. Nevertheless, because they are definitively mentioned in the DWU, they are a part of Category:Time-Space Visualiser and not a behind-the-scenes category.

To make this category more useful, it should only be used as a container for other subcategories, like category:Songs from the real world.
