Network on the telly, with "the” (4)
I believe the answer is:
beeb
'network on the telly with the' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for beeb that I've seen before include "Informally, the British broadcasting service" , "Old microcomputer" , "BBC, familiarly" , "It broadcasts" , "BBC (informally)" .)
