One of uses of this would be an old show I have watched tons of times but still find entertaining. I think Seinfeld is a good example. I have the entire series that I have ripped. I can just sit if I am chilling for a bit or I am in and out of the house while grilling I can flip it on for background noise. Although, I very often come in and a particularly funny part is on and I end up sitting down to watch it! lol
I think old shows like Friends, How I Met Your Mother are other good examples, at least in my scenario.
