Urge to identify a section of the media (5)
I believe the answer is:
press
I believe this clue is a double definition.
'urge' is the first definition.
(I've seen this before)
'a section of the media' is the second definition.
'to identify' is the link.
(Other definitions for press that I've seen before include "Reporters" , "Smooth" , "Crowd closely" , "Newspapers - bring weight to bear" , "Railroad" .)
