Show on television initially in the money (8)
I believe the answer is:
pretence
'show' is the definition.
(I've seen this before)
'on television initially in the money' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'initially' indicates taking the first letters.
'in' indicates putting letters inside.
'the money' becomes 'pence' (I've seen this before).
The initial letter of 'television' is 't'.
're'+'t'='ret'
'ret' inserted inside 'pence' is 'PRETENCE'.
(Other definitions for pretence that I've seen before include "Act of imagination" , "False show hiding reality" , "Make-believe, or false claim to merit" , "Affectation" , "False show; make-believe" .)
