Of course, this turns out to be a complicated question. There are adverts and there are adverts - one where you get "commercial breaks" - which is what I had in mind with this question, and the other where there are product placements, "sponsorships" etc. etc. allowing programmes to be provided without commercial breaks. Therefore, I could re-phrase my question - are there any other channels without commercial breaks?
It also turns out that there are a lot of TV channels around the world, and it doesn't seem to be easy to find out if there are commercial breaks or not, and there appear to be plenty of subscription channels which are advert free. Perhaps my question should be - are there any other free-to-air channels without commercial breaks?
Of course, this post seems to be turning into a list of questions rather than a list which answers a question. A first stab gives this list:
| Country | Channels |
| UK | BBC |
| Denmark | DR |
| US | PBS |
| Australia | ABC |
I'll come back to this another time and see if I can find out more. Couple of useful links:
