I wonder if someone could answer a question I have. I recently went to watch the new film release - Hitchhikers Guide To The Galaxy, and noticed this near the start of the film:

As you can see, Arthur Dent, the main character in the film appears to work at the BBC and has a BBC staff card. My question is, does anyone know what his occupation is exactly. I don't recall any previous detail being given in either the book or TV series to his actual occupation.
So . . . any ideas?
