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 "The ratings for the first two episodes of season eleven fell 16–21% in overall viewer numbers and 24–27% in the 18/49 demo, while the season finale fell 27% in total viewer number and 30% in the 18-49 demo.". Is that enough to answer the question?
Answer: no
