Some game show network (4)
I believe the answer is:
mesh
'network' is the definition.
('mesh' can be a synonym of 'network')
'some game show' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'MESH' is hidden within 'game show'.
(Other definitions for mesh that I've seen before include "Entangle, entwine" , "Get in harmony with" , "Netting; engage" , "Trap" , "Work well together" .)
