I watch just always the same three channels. All of them got no adverts at all, there ist just little time used instead of adverts for the upcoming program on the day or the next days. It is german Tv. And on those channels most of the day are just documentary. it is rare that there would not be something that will not be a documentary on all three channels. I watch from the internet. I also can watch program with adverts but I so hate it. Reminds me of how stupid Tv can be if I need to see adverts.
