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.
never underestimate the rest of the world more speciifcally third world countries with the fact that there are many smartphone providers actually giving out really cheap phone offers and people with poverty usually compensate the lack of owning PC or laptops with smartphone which could easily increase the amount of internet connected devices in a household. The data in my opinion by any means is not skewed.
