@Walter Hinteler,
When I still had my tv, I had gotten down to just watching the Tour d'France and the Giro d'Italia bicycle races (primarily for the scenery), the yearly Westminister dog show, and that's about it, except back then I did use it to watch some movies via vcr or dvd. Mostly I still kept the tv for when my niece would travel upstate to stay with me for a week.
I watched tv for a long time as a kid, but after I turned sixteen and got an after school and weekend job, I tended to prefer reading once I got home and did my homework. I did like Bonanza though, whenever that was.
I also preferred movies in theaters, and husband and I really got into "art house" theaters for a bunch of years.
On when I would stop watching something, back when I did do tv, I would act on my impatience easily. My father and mother and my larger family were involved in the movie and tv business, so that might have been part of it.
On a series that I liked and still almost remember - The Glittering Prizes, a British series with the actor Tom Conti; the author was Frederic Raphael. There was a book too.
