What do you think makes people stay with one streaming service instead of switching to another?

There are so many options now that I wonder what actually makes a service stand out in the long run. Having a big library is obviously important, but I don’t think that’s the only thing people care about. Things like the overall experience, video quality, reliability, pricing, and how easy it is to find something to watch probably matter too.

I’m curious what other people think from a business point of view. If you were building a streaming service today, what would you focus on first to keep customers around instead of constantly losing them to competitors?
