Broadcast, air (8)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
televise
This clue is a double definition.
'broadcast' is the first definition.
(televising is a kind of broadcasting)
'air' is the second definition.
(televising is a kind of airing)
(Other definitions for televise that I've seen before include "Show" , "Broadcast visual images" , "Put on TV (S, not Z)" , "Air, broadcast" , "Put on the box" .)
