Is there a term for phrases which were once literal but now figurative?

We still hang up the phone, even though we really only push a button, not suspend it in a cradle.

Sometimes we tape a television series, even though the DVR does the heavy lifting, not the analogue insides of a VCR.

Is there a term for these words and phrases? I'm not sure about using words like obsolete or archaic, because the methods they describe may be, but the phrases themselves are not.

Perhaps the term you're looking for is "anachronistic". Although it is usually applied to objects in fiction, it could easily apply to a phrase whose literal meaning is now meaningless.
