Introduce broadcast award for business (10)
I believe the answer is:
enterprise
'business' is the definition.
(thesaurus)
'introduce broadcast award' is the wordplay.
'introduce' becomes 'enter' ('enter' can be a synonym of 'introduce').
'broadcast' indicates a 'sounds like' (homophone) clue (how the word might sound on the radio or TV).
'award' becomes 'prize' ('prize' can be a synonym of 'award').
'prize' is a homophone of 'prise'.
'enter'+'prise'='ENTERPRISE'
'for' acts as a link.
(Other definitions for enterprise that I've seen before include "Get-up-and-go - venture" , "Data may be on-board here" , "drug business" , "New project" , "Project, undertaking" .)
