C3PO satisfied TV show's gauge of audience approval (10)

I believe the answer is:

clapometer

I'm a little stuck... Click here to teach me more about this clue!

'gauge of audience approval' is the definition.
(a clapometer measures applause)

'c3po satisfied tv show's' is the wordplay.
I cannot quite understand how this works, but
'satisfied' could be 'met' (as in 'met the conditions of his contract') and 'met' is found within the answer.
'show' could be 'er' (US medical drama) and 'er' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

I've seen this clue in The Independent.
