Publicity ad, for short (5)

I believe the answer is:

promo

'publicity ad for short' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for promo that I've seen before include "Brief publicity" , "Encouragement" , "Advertising film/video" , "publicity event" , "advertisement" .)

I've seen this clue in the Newsday.com and the Newsday.
