Passage from broadcast losing millions (7)
I believe the answer is:
transit
'passage' is the definition.
(I know that passage can be written as transit)
'broadcast losing millions' is the wordplay.
'broadcast' becomes 'transmit' (synonyms).
'losing' is a deletion indicator.
'millions' becomes 'm' (abbreviation).
'transmit' with 'm' taken out is 'TRANSIT'.
'from' is the link.
(Other definitions for transit that I've seen before include "Movement from place to place" , "To pass through/across" , "Travel" , "Crossing - passage" , "Act of passing across" .)
