Broadcast from underworld with acclaim (10)
I believe the answer is:
distribute
'broadcast' is the definition.
('distribute' can be a synonym of 'broadcast')
'underworld with acclaim' is the wordplay.
'underworld' becomes 'dis' (I've seen this before).
'with' means one lot of letters go next to another.
'acclaim' becomes 'tribute'.
'dis'+'tribute'='DISTRIBUTE'
'from' acts as a link.
(Other definitions for distribute that I've seen before include "Give out" , "spread" , "Pass round" , "Supply" , "Hand or share out" .)
