Radio travel broadcast is a promotional feature (11)

Ross

I believe the answer is:

advertorial

'a promotional feature' is the definition.
(editorial content which advertises something)

'radio travel broadcast' is the wordplay.
'broadcast' indicates anagramming the letters.
'radio'+'travel'='radiotravel'
'radiotravel' is an anagram of 'ADVERTORIAL'.

'is' acts as a link.
