The Internet is a Series of Tubes

Internet adoption tends to progress in phases: early rapid adoption in urban areas and by relatively well-educated and higher-income households, then transitioning to a slower pace once between 70 and 85% of households subscribe. For example, in a 2013 survey, the Pew Research Internet Project found that approximately 15% of the adult population does not use the Internet; those least likely to use the Internet include “senior citizens, adults with less than a high-school education and those living in households earning less than $30,000 per year.
