Railroads displaced older forms of transportation because it was much more efficient, it was faster, & it could carry a lot more, and go farther than most animals. (that time there were no well-functioning cars).

Internet displaced communication, because it was faster (well sometimes), and allowed you to access a lot more at once. The internet allowed people to talk without facing each other (or having to physically go to a phone or anything else) & gave people access to millions of resources and information that is found all around the world


hope this helps
