TV set remained off for commercial (13)

I believe the answer is:

'commercial' is the definition.
(thesaurus)

'tv set remained off' is the wordplay.
'off' is an anagram indicator.
'tv'+'set'+'remained'='tvsetremained'
'tvsetremained' anagrammed gives 'ADVERTISEMENT'.

'for' is the link.

(Other definitions for advertisement that I've seen before include "Bill" , "Commercial promotion" , "Public promotion" , "trailer" , "Placard" .)

I've seen this clue in The Telegraph.
