Bright bunch working for TV hearing news as it breaks (14)
I believe the answer is:
intelligentsia
'bright bunch' is the definition.
(group of bright or intelligent people)
I can't explain the rest of the clue.
(Other definitions for intelligentsia that I've seen before include "they think" , "Smart people" , "Eggheads" , "Educated or cultured classes" , "Bright bunch" .)
