I do find the chart misleading. Take the telephone for example. It required a HUGE infrastructure in what was still mostly a rural country at the time, and it's growth was stymied by two World Wars that put priorities elsewhere. Plus, while a convenience, there was nothing "necessary" about the telephone. It was also expensive. This is an excerpt from a NYC phone book circa 1920. The columns are the charges for the first 3 minutes, then every additional minute. Not exactly cheap.
Everything else on this chart was dependent on the growth of the electrical grid, so naturally the curve could not be much faster than that was, but if it came later than the grid then it was much easier to spread.
Urbanization and its usefulness in business has made the spread of the Internet faster, but not equally. Nearly 50% of the folks that work with me in IT in our rural hospital system (just 30 miles from Atlanta) cannot get Internet above basic DSL speeds.
