On Monday, Netflix revealed its top 10 original TV shows of all time based on viewing hours, a different measurement than what it typically shows the public.
Netflix co-CEO Ted Sarandos pulled the curtain back on the data at the annual Code Conference. He broke down Netflix's most popular TV seasons based on the total amount of hours watched in their first 28 days of release.
"This is us being super transparent with you, don't tell anybody," Sarandos said with a laugh when showing off the numbers. He added that Netflix is starting to reveal more information about the viewership of its shows, explaining, "Everyone wants to know, 'is my show being watched?'"
Typically, when Netflix announces viewership numbers for a TV show, it reveals the number of households that watched at lesat two minutes of a series in its first month. That metric doesn't account for people who might not complete an episode or a series.
"Bridgerton" is Netflix's biggest series based on both metrics.
But Sarandos also teased on Monday that Netflix's new Korean-language original series "Squid Game" - which released on Sept. 17 - is on track to be its biggest show of all time.
Below are the Netflix original TV seasons that gained the most viewing hours in their first 28 days of release:
