Media machine? (5)
I believe the answer is:
press
This clue is a double definition.
'media' is the first definition.
(the press is part of the media)
'machine?' is the second definition.
(I know that press is a type of machine)
(Other definitions for press that I've seen before include "Iron (clothes)" , "Squeeze out (juice/oil)" , "harass > crowd" , "Put creases in" , "Fourth estate" .)
