Runs a live broadcast, worldwide (9)
I believe the answer is:
universal
'worldwide' is the definition.
(I know that worldwide can be written as universal)
'runs a live broadcast' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'runs'+'a'+'live'='runsalive'
'runsalive' anagrammed gives 'UNIVERSAL'.
(Other definitions for universal that I've seen before include "for general viewing" , "Of worldwide scope" , "Found everywhere" , "Everywhere applicable" , "blanket" .)
