The New York Times piece about Playboy dropping pictorials of naked women starts with "a top editor" at the magazine going to see 89-year-old Hugh Hefner to check that it's OK.
In British magazine culture there's only one top editor. That's the editor.
I've never understood how American magazines can have so many people called editor, particularly when the staffs are as shrunken as they must be now.
You generally find the actual the editor is called Managing Editor or Editor-in-chief.
You also find they have no power.
