Netflix is infamously tight-lipped about its ratings, refusing to share any hard numbers on how many people are actually watching its original series. But in a presentation to press on January 13 at the TCA Press Tour, NBC's in-house "numbers guy" Alan Wurtzel put forth an "in beta" estimate of Netflix's top-secret ratings for the last four months of 2015, produced from a sample of 15,000 people, Digital Spy said.

According to his stats, Marvel's Jessica Jones pulled in 4.8 million viewers per episode in the adults 18-49 demographic; Aziz Ansari's Master Of None brought 3.9 million, and Narcos 3.2 million. Over on Amazon, its highest-rated show to date Man in the High Castle managed 2.1 million.

Those numbers come from Symphony Advanced Media, a company which measures TV viewership using audio content recognition technology – that's phone software which monitors what its users are watching by identifying soundtracks.
