The BBC One drama Sherlock has swept the board at the Bafta Cymru awards, winning five categories.
Sherlock, the modern-day retelling of Sherlock Holmes commissioned by BBC Cymru Wales, won best television drama and best director for Euros Lyn.
The best actor award went to Stuart Brennan for his role as the Welsh boxer Howard Winstone.
Meanwhile, BBC Wales's Week In Week Out won an award for its programme University Challenged.
The 20th annual awards was held Wales Millennium Centre in Cardiff on Sunday.
BBC Cymru Wales won 15 awards, while independent production company Rondo Media won in four categories, closely followed by Fiction Factory with three awards.
Programmes on the Welsh language channel S4C claimed prizes in eight categories.
But it was Sherlock's night.
Starring Benedict Cumberbatch and Martin Freeman, it won awards for best television drama, best director (fiction), production design, hair and make-up and photography (fiction).
It follows success at the Bafta TV Awards in London last week, when Sherlock won two prizes.
BBC Wales's investigative series Week In Week Out picked up a Bafta for its University Challenged programme.
It examined the way in which the University of Wales validated courses in overseas institutions.
Collecting the award, the programme's producer and director, Nick Skinner, said: "(I've) got to say thanks to Ciaran Jenkins (the programme's presenter) first of all. Fantastic presenter, but he was the guy who came up with the idea. He was the guy that smelt a rat at the university."
The best actor award went to Stuart Brennan for his role in Risen: The Howard Winstone Story. Winstone, from Merthyr Tydfil, died in 2000.
Brennan said: "Howard Winstone was an incredible man. Taking on this project was a huge undertaking for us."
He added that it involved "incredible people", "a fantastic cast" and "an incredible crew". He also thanked the Winstone family.
Television producer Gareth Gwenlan, who worked on the BBC comedies Only Fools and Horses, The Fall and Rise of Reginald Perrin and To the Manor Born, received a lifetime achievement award for his contribution to the British and Welsh television industry.
The Hollywood actor from Cardiff, Matthew Rhys, was also honoured with The Sian Phillips Award, while BBC Wales' Snowdonia 1890 was given the Gwyn Alf Williams Award.
Mali Harries won best actress for her role in The Indian Doctor, which was made by Rondo for the BBC, and set in a Welsh mining village in 1963.
Angharad Mair, of Welsh language magazine programme Wedi 7 on S4C, was awarded best presenter, while comedian Rhod Gilbert's Work Experience for BBC Wales won best factual series for his trials with the Bin Men.
