What do your fitness tracker, your fridge, car, thermostat, phone, TV, gaming console and the weather service have in common? They are all connected, or soon will be. These connected devices are referred to as the Internet of Things (IoT) and — for those who’ve been living under a rock — it’s the next big thing. Just how big depends on the source. It’s estimated that, by 2020, the IoT will be worth between $7 and $19-trillion as an industry.
