The new Nielsen streaming measurement also found that nearly 11 million adults in the key 18-49 demo watched the second season of the Netflix hit and that 361,000 subscribers binged on the entire season within 24 hours of its release. Because Netflix doesn’t release ratings data, it’s still unclear if these numbers are authentic, especially since Nielsen only counts TV set viewership.
