Made live broadcast historic? (8)
I believe the answer is:
medieval
'historic?' is the definition.
(from the Middle Ages)
'made live broadcast' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'made'+'live'='madelive'
'madelive' with letters rearranged gives 'MEDIEVAL'.
(Other definitions for medieval that I've seen before include "Belonging to the Middle Ages" , "Relating to the Middle Ages" , "Of an earlier period" , "Am veiled in style of the middle ages" , "Of the middle ages, or really old-fashioned" .)
