Length of tv shows and movies

I wonder if tv streaming companies like Netflix and Amazon Prime pay much attention to the length of their shows and movies.  We like to clean up the dinner dishes and stream something at 7 PM.  After about an hour, we like to have me read aloud, usually from a book selected by her book club or mine.  After another hour, we like to watch a 2nd streaming show and go to bed at 10 PM.

We do sometimes watch for about an hour and return to the place we left off on the next evening.  We often turn away from shows that are more than two hours. None of this is set in stone but it is fairly firm.

I was pleased to see a line of choices on Netflix labeled "shorter shows".  We found the show "Reba" that fit our schedule nicely.  Most of the Call the Midwife shows fit unless we stumble onto a Christmas special.
