‘Stranger Things': 15.8 Million Watched Season 2 Premiere in First Weekend, Nielsen Says

And 361,000 people consumed the entire run on Day 1, per new streaming metric

Nielsen promised us streaming TV ratings, and now we’ve got some. And these are big ones — both in terms of tune-in tallies and the specific data set’s significance to the industry. The ratings currency company says 15.8 million people watched Netflix’s “Stranger Things” Season 2 premiere episode over its opening weekend.

Of that overall Live + 3 Day (of sorts) audience, nearly 11 million members come from the all-important adults 18-49 demographic. While subscription service Netflix doesn’t sell ads, they still target the folks with disposable income. Young adults never go out of style.

Additionally, 361,000 people watched all nine of the new hour-long episodes on Day 1. It’s like, get a life, you guys.

Across Friday, Saturday and Sunday, the average number of “Stranger Things 2” episodes that a viewer from the key age-range in the U.S. watched was 2.9. That means those who started the season binged nearly 3 episodes. And on just Saturday alone, consumers 18-49 devoured an average of 3.2 episodes.

Additionally, according to Nielsen Social Content Ratings data, there were 7.2 million social interactions across Facebook and Twitter about “Stranger Things” over the second season’s first three days.

Netflix, which does not share any viewership information as a rule, did not immediately respond to TheWrap‘s request for comment on Nielsen’s numbers. If the past is any indication, it is unlikely that Reed Hastings and Ted Sarandos are pleased with their audience size being shared — even as good as these numbers are.

Finally, we have some per-episode statistics to share.

Crunching some numbers below, “Stranger Things 2” averaged a per-episode tally of 8.8 million total viewers. That’s admittedly a flawed figure, however, as only an insane person would skip ahead to start at the final few episodes, and three days is far to short a timespan for the average fan to consume an entire season. Still:

    • “Chapter Two” averaged 13.7 million viewers P2+ and 9.6 million people 18-49 viewing over the first three days of its availability
    • “Chapter Three” averaged 11.6 million viewers P2+ and 8.1 million viewers 18-49 viewing over the first three days of its availability
    • “Chapter Four” averaged 9.3 million viewers P2+ and 6.6 million viewers 18-49 viewing over the first three days of its availability
    • “Chapter Five” averaged 8 million viewers P2+ and 5.6 million viewers 18-49 viewing over the first three days of its availability
    • “Chapter Six” averaged 6.4 million viewers P2+ and 4.5 million viewers 18-49 viewing over the first three days of its availability
    • “Chapter Seven” averaged 5.3 million viewers P2+ and 3.7 million viewers 18-49 viewing over the first three days of its availability 
    • “Chapter Eight” averaged 4.9 million viewers P2+ and 3.4 million viewers 18-49 viewing over the first three days of its availability
    • “Chapter Nine” averaged 4.6 million viewers P2+ and 3.2 million viewers 18-49 viewing over the first three days of its availability

“Stranger Things 2” was dumped by Netflix in its entirety on October 27.
