Screenings of birthmarks essentially down by 88% (6)

Ross

I believe the answer is:

movies

'screenings' is the definition.
(film screenings)

I can't explain the remainder of the clue.

(Other definitions for movies that I've seen before include "Films in America" , "Cinema films" , "Flicks" , "big-budget features" , "Informally, films shown in cinemas" .)

I've seen this clue in The Independent.
