A TV and broadcast age offering benefit (9)
I believe the answer is:
advantage
'benefit' is the definition.
(I've seen this before)
'a tv and broadcast age' is the wordplay.
'broadcast' is an anagram indicator (letters scattered or cast around).
'tv'+'and'='tvand'
'tvand' with letters rearranged gives 'dvant'.
'a'+'dvant'+'age'='ADVANTAGE'
'offering' is the link.
(Other definitions for advantage that I've seen before include "Use" , "More favorable position" , "Upper hand, benefit" , "Favourable circumstance" , "Benefit, profit" .)
