I think it would be cool if television didn't have certain time slots for shows. I think it would be neat to be able to sort of rewind days, weeks, months or years of television shows and go back to an episode or favorite show and rewatch it. Many times there isn't anything on tv that people want to watch and this would guarantee that you could! For example, if I wanted to rewind to an episode of my favorite soap from a month ago or year ago, I would be able to.
