Living in Wales there’s some real low-budget TV being made “regionally”. I say that in inverted commas because Wales is classified as a broadcast region rather than a “country” when broken down across UK broadcasting regions. Wales has its own Channel 4 called S4C (Sianel 4 Cymru - "Wales’ Channel 4), which is part funded by the BBC, in addition to the UK Channel 4 which is independent of the BBC. Simple!
That aside a lot of programming, particularly for children, is translated from English creations, but there’s some borderline cursed stuff being made.
Obviously all these clips will be in Welsh so your mileage may vary with these.
This clip is a song about the weather from the early 90s. I don’t recall whether it was a regular thing but I imagine that it would have been used as an intro to a weather segment on kids TV given that they probably blew quite a lot of their budget on making it. The bird is called Wcw (Oo-coo) which is the Welsh onamatapoeia for the noise a cuckoo makes, and the “weithiau mae’n braf, weithiau mae’n heulwen” hook means “sometimes it’s nice, sometimes it’s sunny”. Not sure whether this is a dig at Wales’ weather being almost exclusively “pissing it down”. Also the video weirdly namedrops my dinky hometown.
Moving onto the late 90s is this deeply embarrassing kids game show, Nics Nain (literally translated as Nan’s Knickers). I’ve no idea how this was commissioned but whoever thought that was a good theme must’ve been high as heck. I think it only ran for one, maybe two series - it was pretty terrible. My school was chosen to go once and for some reason the teachers picked people that weren’t known for their athleticism.
Moving onto programmes for adults is the BBC’s longest running soap opera across the UK, Pobl y Cwm (“Pob l err cwm” - literally translated as “The Valley Folk/People”). I found a subtitled promo!
Finally something more contemporary, and genuinely excellent is Hinterland / Y Gwyll, which as far as I know is still on Netflix. Essentially a detective drama set in the seaside town of Aberystwyth (and is a much better representation its namesake from Koudelka!). Everything is filmed twice, once in English and once in Welsh which is pretty wild. Anyway, this is something that I would actually recommend watching.
