Comparing the US experience with other parts of the world, you see a dramatic difference in the amount of time Americans had to internalize life with the phone. I worked on international VOIP deployments in the late 90s and early 2000s and some of the populations were going from no phone access to first cellphones / very expensive rates to affordable rates, all in a few years.
Yes, you don't even have to go to the more remote or significantly developmentally behind countries. In Hungary (in Budapest, not some remote rural place), we didn't have a landline phone up until the mid-to-late 90s. It was not unheard of, just difficult to get, you'd be on the wait list for long. There were street payphones though, so we could call relatives who got theirs earlier. We went from getting our first landline to getting broadband Internet within a single decade (mid 1990s to mid 2000s).
