Broadcast exotic arts etc (7)
I believe the answer is:
scatter
'broadcast' is the definition.
(I've seen this before)
'exotic arts etc' is the wordplay.
'exotic' indicates an anagram.
'arts'+'etc'='artsetc'
'artsetc' with letters rearranged gives 'SCATTER'.
(Other definitions for scatter that I've seen before include "Break up" , "Throw in various directions" , "Disseminate" , "Strew randomly" , "Throw loosely about" .)
