How mobile is forcing us to change the way we measure the Internet - Jon Russell, The Next Web

It is a metric that is well used across the world in research, analysis and reporting but it is time that the technology world stopped leaning so heavily on Internet penetration. The statistic is one of a number that are at a risk of becoming out-dated in today’s multi-platform Internet. Internet penetration rate denotes the percentage of a (usually) national population that has access to the Internet in their home. The figure is calculated by studying customer figures from fixed-line Internet service providers (ISPs), and – though not 100% accurate – it is a reliable estimate of the reach of fixed, home web access. Today’s average Internet user could access the web from as many as five different locations in just one single day.
