Sports logo since 1972 (6)
I believe the answer is:
swoosh
'sports logo since 1972' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for swoosh that I've seen before include "Noise of a sudden rush of air" , "Noise of movement" , "Noise produced by a sudden rush of liquid" , "Sound of rushing air or liquid" .)
