Russell T Davies' It's a Sin has broken a big All 4 record.
The five-part drama, which was written by the former Doctor Who showrunner and follows a group of gay friends living in London amid the '80s AIDs epidemic, was released on the Channel 4 streaming service at the end of last month to rave reviews.
On Tuesday (February 2), Channel 4 revealed the series has already had 6.5 million views on All 4 — making it the biggest ever instant box set.
The phenomenal stats also make It's a Sin the streamer's third biggest series to date and most binged new series ever, while the first episode has become All 4's most popular drama launch on record.
Those are some pretty impressive stats.
Additionally, the accolades of It's a Sin contributed to All 4 achieving its biggest ever month of streaming in January 2021, with an increase of 91% more viewers than the same month last year.
During its first week on air, the show's hashtag #ItsASin was also seen by over 83m people – and consolidated viewing figures across the same time frame make it Channel 4's best drama launch for young viewers since the Sarah Lancashire drama Kiri in January 2018.
"The extraordinary performance of It's a Sin is a reminder that powerful drama with something important to say about the world can also be commercially successful," said All 4's Chief Content Officer, Ian Katz.
"It has also demonstrated how our strategy of box-setting shows on All 4 can bring a greater combined linear and digital audience to a show than a traditional release pattern."
The impressive viewing figures come as It's a Sin gears up for its US release on HBO Max.
If streaming the series simply isn’t enough, you can also buy it on Blu-Ray and DVD later this month.
