I want to know the answer to the following question:
How long did Fox reign in the 18-49 demographics in the Nielsen ratings?
All the background I'm provided with is that "For the first time in eight years, American Idol lost the leading position in both the total viewers number and the 18/49 demo, coming in second to NBC Sunday Night Football, although the strengths of Idol in its second year in the Wednesday-Thursday primetime slots helped Fox achieve the longest period of 18-49 demographic victory in the Nielsen ratings, standing at 8 straight years from 2004 to 2012.". Is that enough to answer the question?
Answer: yes
