No, I really don't watch much TV, - actually, I watch hardly any TV - and almost never for what would be termed entertainment. Actually, I, personally, have never owned a TV set, and whole months of my life go by - usually when I am abroad - when I do not watch a single TV programme for months on end. And no, I don't miss it. At all.
Quite seriously, when I am in a house with a TV, I will watch news, current affairs or documentaries, and nothing else. In truth, I hardy ever watch movies, - least of all anything recent from the US - and I find most of what is called 'entertainment' tedious and boring. More to the point, I find it annoys and irks me - it seems to me a colossal waste of time and, anyway, I spend enough time facing a screen when I am online. In any case, I do not view 'entertainment' on TV as something which is relaxing. For relaxation, I listen to music, (which I love), or read.
And yes, in general, I prefer fact to fiction, although I will read fiction.; sometimes, for relaxation, I read fantasy/scifi; otherwise, when I am home and have time available, I will read more 'serious' fiction.
However, mostly, as you have observed, I tend to read fact. I used to teach history and politics, and still, to some extent, work in this field, and, it is something I find enormously interesting. I am the sort of person who visits ancient cities and towns on holiday - I like theatres, pubs, museums and coffee shops
..and book shops
