I need to know this for an essay I'm doing. I thinks media might work but I'm not really sure. Do you have any suggestions?
try works. I don't think there's a term that covers specifically books and movies other than just naming them as what they are.
A piece of art, a play piece, a piece as in script, a piece as in book, and a movie (piece).
fiction is a good word to use for describing both books and movies
Might be a fairly slang, even sarcastic, way of describing such entertainment materials.
