Netflix: Users spent 812 million hours watching The Night Agent
Netflix has released viewer data on 99% of its catalogue for the first time.
Users around the world watched The Night Agent for 812m hours, making the political thriller its most viewed show in the first half of this year.
The streaming giant has been criticised for not being transparent about how content performs on its platform. the criticism was central to this year's Hollywood strikes, which paralysed the film and television industry for several months.
Actors and writers have been demanding higher royalties for shows that performed well on streaming platforms.
On a conference call with the media, co-chief executive Ted Sarandos acknowledged that the lack of transparency about the popularity of its shows had led to distrust in the creator community.
"This is a big step forward for Netflix and our industry," the company said in a blog post
"We believe the viewing information in this report... will give creators and our industry deeper insights into our audiences, and what resonates with them."
Hollywood's creative community relies on viewing figures from audience data firm Nielsen - released annually - for traditional broadcast and cable television.
The what we watched report ranks 18,000 titles by the amount of hours viewed between January and June this year. The company said it will now release the report every six months.
Covering nearly 100 billion hours of viewing time, other shows that featured prominently on the list included Ginny and Georgia, Gilmore Girls, Seinfeld, Friends and The Office.
"Success on Netflix comes in all shapes and sizes, and is not determined by hours viewed alone. We have enormously successful movies and TV shows with both lower and higher hours viewed. It's all about whether a movie or TV show thrilled its audience — and the size of that audience relative to the economics of the title," the company said.
With almost 250 million subscribers globally, Netflix is the largest streaming service in the world.
Since 2021, it has been releasing weekly Top 10 and Most Popular lists, which show the most-watched movies and TV shows in English and other languages.
Netflix said that more than half of the titles released this year appeared on the weekly Top 10 lists. The What We Watched report showed 55% of Netflix viewing came from original films and series and 45% from licensed titles, according to Mr Sarandos'.
Last year, Netflix launched a separate service with adverts, which requires more transparency because advertisers want information about the popularity of content.
Netflix's engagement report included more than 18,000 titles that represent 99 percent of all options on the platform and in total, nearly 100 billion hours were watched between January and June.
The Night Agent was by far the most successful with 22 percent more views than the program in second place.
The Gory came in third place with 622 million hours watched.
The first season of comedy-horror show Wednesday, which came out in November 2022, racked up 508 million hours of viewing and Queen Charlotte: A Bridgerton Story totaled 503 million hours.
You: Season 4, La Reina del Sur: Season 3 and Outer Banks: Season 3, had 441 million hours, 430 million hours and 403 million hours viewed, respectively.
The first season of Ginny & Georgia was watched for 302 million hours and FUBAR: Season 1 rounded off the top 10 with 266 million hours watched.
