Downmarket (7)
I believe the answer is:
lowbrow
'downmarket' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for lowbrow that I've seen before include "Non-intellectual person - observe forehead" , "Downmarket" , "Hard mass in wood, shore bird" , "Uncultured (person)" , "Not highly (or pretentiously) cultured" .)
