There's nothing upside down about the record number of viewers who tuned in to the third and most recent season of Stranger Things.

According to Netflix's quarterly earnings report, Season 3 of the sci-fi hit is the streaming service's most-watched original series of all time, with an estimated 64 million views. Netflix is citing views recorded four weeks after the show's July 4 premiere. In order to be counted as a "view," a member of a household has to watch 70 percent of an episode or feature film.

The impressive number tracks with the ratings results Netflix previously released on Stranger Things Season 3. The show apparently attracted 40.7 million member accounts all over the world immediately after its summer debut. And another 18 million member households binged all eight episodes in a matter of days.

Nielsen also confirmed the success of Season 3, trumpeting a 21-percent increase in viewership in the first four days when compared to Season 2. But Netflix doesn't use Nielsen numbers because the ratings service doesn't count viewers outside of the U.S. and does not measure viewing on certain devices.

Stranger Things Seasons 1-3 are available on Netflix.
