My family all have differing tastes in entertainment. My kids wouldn’t want to (and we wouldn’t let them) watch the same things my wife and I watch. With the varied tastes in the house, we keep multiple services around. For folks who don’t have kids and have more similar tastes between people in the house, having 1 or 2 services at a time, would make more sense.
