Over 200 billion devices are estimated to be connected to the internet by 2020 worldwide. This includes an array of new devices hitting global markets in addition to the existing pool of devices. This number may seem staggering because it would mean that each human would need almost 25 devices for the math to add up. If you account for the phones, watches, computers, cars, TVs, etc. this number is relatively small and continues to increase over time. This is because almost all devices and physical products will have some sort of internet connection to perform tasks better. For example, a smart refrigerator can tell the temperature of the food in the fridge while informing about weather conditions and saving grocery lists.
