inset

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

'feature added to a magazine?' is the definition.
I can't tell whether this defines the answer.

'popular tv' is the wordplay.
'popular' becomes 'in' (something that's 'in' is fashionable).
'tv' becomes 'set' (television set).
'in'+'set'='INSET'

Can you help me to learn more?

(Other definitions for inset that I've seen before include "Small picture within borders of another" , "Intimidated" , "Small map within larger; teacher training day" , "Place within" , "Gore" .)
