Aimed to reorganise means of communication (5)
I believe the answer is:
media
'means of communication' is the definition.
(mass media)
'aimed to reorganise' is the wordplay.
'to reorganise' is an anagram indicator (I've seen 'reorganized' mean this).
'aimed' is an anagram of 'MEDIA'.
(Other definitions for media that I've seen before include "Aimed (anag.)" , "oils as examples" , "journalists' outlets" , "Press, TV etc" , "Mass communicators" .)
