The Abandoned Engineering TV Documentary Series
Recently whist playing with Galaxus TV which is just free to air television, made available via Galaxus rather than a satellite dish I have been able to revert to the habit of watching niche documentaries, as I used to years ago, when I lived in a house with a satellite dish.
The beauty of broadcast television, in contrast to streaming services, is that you have high quality content that was good enough for broadcast. The other advantage is that content is available two to three episodes per day, rather than all at once as is the case with Netflix, among other platforms.
