Netflix drama Adolescence has become the first streaming show to top the UKs weekly TV ratings, beating BBC shows like The Apprentice and Death in Paradise in the latest official rankings.
The first episode of Adolescence was watched by 6.45 million people in its first week, according to ratings body Barb.
That is the biggest audience for any streaming TV show in the UK in a single week, beating the 6.3 million who watched Fool Me Once on Netflix in January 2024.
Adolescences achievement in breaking the dominance of the traditional broadcasters at the top of the UKs weekly TV ratings will be seen as another milestone in the growth of Netflix and streaming.
The second episode of Adolescence was seen by 5.94 million, with BBC Ones The Apprentice and Death in Paradise third and fourth respectively in the weekly chart with almost 5.8 million each.
Adolescences third episode was fifth in the weekly ratings with 5.14 million, while the fourth and final instament was seen by 4.65 million.
About 17 million UK homes have Netflix subscriptions.
Adolescence quickly became the most talked-about show of the year so far after it launched on 13 March.
It won acclaim from critics and viewers for its hard-hitting story of a 13-year-old boy who is arrested on suspicion of murdering a girl from his school, with the drama made more intense by filming each episode in a single shot.
Its cast has come in for particular praise, including newcomer Owen Cooper as young Jamie, and Stephen Graham as his dad.
The show has also sparked a national conversation about the impact of social media and "manosphere" influencers.
Prime Minister Sir Keir Starmer told BBC Radio 5 Live in an interview broadcast on Monday: "Theres a reason why the debate has suddenly sparked into life - a lot of people who work with young people at school or elsewhere, recognise that we may have a problem with boys and young men that we need to address."
Adolescence is now among the programmes with the highest seven-day ratings so far this year, behind the BBCs The Traitors, Call The Midwife and the Gavin & Stacey: A Fond Farewell documentary.
It is also some way behind ITVs drama Mr Bates vs the Post Office, which made a similar impact last year, and was watched by 10 million people in its first week.
Barb began including streaming data in its ratings in November 2021.
