In contrast, other popular historical dramas like The Crown and The People v. O. J. Simpson (aka American Crime Story) barely reached that at their peaks.
Ratings for Chernobyl started high and stayed consistent.
Even more impressively, every single episode of Chernobyl has been rated by IMBD users at 9.5 or higher - a feat which, for four consecutive episodes, had previously only been achieved by Breaking Bad, and that was for its final four episodes.
Given the subject matter, and the fact that it's an historical drama as opposed to an epic fantasy like Game of Thrones (which has an average rating of 9.4/10), this level of success is relatively unheard of.
The show has also caused a massive swell of interest in the real-world events of Chernobyl with web traffic for the disaster on Wikipedia increasing 56-fold since the start of the year.
The series prompted a huge amount of interest in the real world event.
Chernobyl is available to stream on Neon, with the final episode screening tonight at 9:30pm on SoHo. Listen to The Chernobyl Podcast here or on iHeartRadio
