Boss on outskirts of Idaho where TV show is made? (6)
I believe the answer is:
studio
'where tv show is made?' is the definition.
(TV studio)
'boss on outskirts of idaho' is the wordplay.
'boss' becomes 'stud' (both can mean a metal decoration).
'on' means one lot of letters go next to another.
'outskirts of' means to remove the middle letters (only letters on the outskirts).
'idaho' with its centre taken out is 'io'.
'stud'+'io'='STUDIO'
(Other definitions for studio that I've seen before include "Workplace for artist, photographer etc" , "Artist's workroom - film company" , "Where one may paint" , "RA's workroom" , "Elstree area" .)
