Directed media to reform (5)
I believe the answer is:
aimed
'directed' is the definition.
('aim' can be a synonym of 'direct')
'media to reform' is the wordplay.
'to reform' is an anagram indicator (letters in a new form).
'media' is an anagram of 'AIMED'.
(Other definitions for aimed that I've seen before include "Set sights on for a dime" , "Drew a bead on" , "Focused on as target" , "Media (anag)" , "trained" .)
