Earlier quoted context omitted.
The trick is to watch the smaller "third programmes" or the programmes with special focus, not the big two (ARD and ZDF). Then you'll see a plethora of really well-made documentations about regions in Germany, regions in the world, culture, archeology etc. The third programmes are also where new comedians, hosts and artists are given a chance to refine their show concepts and prove themselves.
> The trick is to watch the smaller "third programmes" or the programmes with special focus, not the big two (ARD and ZDF). To be fair, The Big One is actually just all "third programmes" with some additional programming such as news.
Take a look at the first column of https://www.tvinfo.de/tv-programm/ard
Pretty much nothing in there is also shown at any third programme. The programmes are almost completely distinct.
Evening news are actually the one part where the third programmes show the same as the ARD.
