Pressure to broadcast match (4)
I believe the answer is:
pair
'match' is the definition.
('pair' can be a synonym of 'match')
'pressure to broadcast' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'to broadcast' becomes 'air' ('air' can be a synonym of 'broadcast').
'p'+'air'='PAIR'
(Other definitions for pair that I've seen before include "Twins" , "item" , "Husband and wife" , "Two ducks in one game of cricket" , "how braces come" .)
