The Voice is going to a hard programme to find people who can sing and speak Welsh and judges who can sing and speak Welsh.

I don’t know how you think S4C has survived for the past 41 years. Don’t forget learning Welsh is compulsory in schools in Wales so even if most people use English as their main language there are plenty of people who can speak Welsh. So when the only broadcast platform they can get on mandates it, they’ll be fine.

As for Gogglebocs, I’ve only ever seen it briefly. But I’d imagine they watch English laungauge programmes as well, as otherwise they’d only ever be watching S4C content which would be quite limited.
