The soap is consistently in the top 20 most watched programmes of the week on S4C,[2] the show currently averaging around twenty thousand viewers per episode.

In addition, a weekly omnibus with in-vision English language subtitles airs on Sunday daytime.

Phil Redmond, creator of Grange Hill, Brookside and Hollyoaks, acted as a consultant to the series on its launch in 1995, and again on its tenth anniversary.

The series is filmed in Menai Bridge, Llangefni, Anglesey and Caernarfon, North Wales, and is produced by Rondo Media (previously known as Ffilmiau Nant).

When it began, the production company converted a disused garage in Dale Street (Welsh name: "Lôn Cilbedlam") in Menai Bridge into a fake row of shops, which includes a café, a hairdresser, a newsagent, a taxi firm, a pizza place and a bar.

Hospital scenes are often filmed in nearby Ysbyty Gwynedd, Bangor, usually in one of the staff hostels.

This was a three-part series chronicling an eventful and comical detention session at Glanrafon high school.
