Broadcast media is sent wild (11)
I believe the answer is:
disseminate
'broadcast' is the definition.
(I've seen this before)
'media is sent wild' is the wordplay.
'wild' indicates anagramming the letters.
'media'+'is'+'sent'='mediaissent'
'mediaissent' is an anagram of 'DISSEMINATE'.
(Other definitions for disseminate that I've seen before include "Broadcast" , "Spread abroad" , "Spread widely" .)
