When do you think online videos will have features of VHS videos: Pause at the exact place the first time, Slow Motion, etc?

I would like no more trial and error, that goes with online videos. Or am I wrong about it? Is there a way of having it stop exactly where I want it?
I am editing this after I got an answer that says that there is such a thing, Netflix and Hulu. I believe they are sites for watching TV shows, I am not sure. But how come after all these years these features are not implemented everywhere?
