Since 2009 There Was A 500% Increase In Internet Traffic. Today, The Average Household Has More Than 7 Internet-Connected Devices, By 2020 There Will Be 6.58 Connected Devices Per Person. With A 7.5 Billion Global Population, Thats 50 Billion Devices.
The basis of this data for me is largely skewed in the sense that there are households mostly in the developed world where a family can have more than 10 internet enabled devices for a family of 5. But using that as a statistics to predict for the entire world is largely over reaching as there are several families spread across the world that internet enabled devices there is not up to 2 because the lack of infrastructure, poverty level, low education among other factors that have continued to mitigate against such penetration.
