TV ratings name (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
nielsen
'tv ratings name' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nielsen that I've seen before include "Carl -, Dan. composer" , "Musician" , "Danish symphonist" , "Carl -, Danish cmpsr." , "Danish composer, Carl (1865-1931)" .)
