Timely media broadcast without delay (11)
I believe the answer is:
immediately
'without delay' is the definition.
(thesaurus)
'timely media broadcast' is the wordplay.
'broadcast' is an anagram indicator (letters scattered or cast around).
'timely'+'media'='timelymedia'
'timelymedia' is an anagram of 'IMMEDIATELY'.
(Other definitions for immediately that I've seen before include "Right now" , "Straight away" .)
