And as always (my favorite): window screens.
They pretty much don't exist in TV & movies because they provide a time-wasting impediment to any scene involving entering or leaving through a window (including "leaving" by getting punched, pushed or shot by a window with a dramatic breaking of glass as the person is flung out through the glass pane).
I've just come to accept that in TV land or Hollywoodland (the world of fictional movie pictures) everybody just has a lot of bugs in their house in the summer, the same way it was before the invention of the window screen.
