IoT is Not New, Just Newer
Rolling back some 40 years, we can identify its roots in "telemetry": big, bulky, expensive, and, compared to today, weak computer devices capable of capturing simple data points and returning them for analysis. Because of their size and cost, if they sat on large and bulky objects, telemetry devices made sense. For starters, ships or rockets aimed at the moon.
Telemetry developed into telematics as the years progressed. Smaller sensor systems may hold telematics goods by boats or trucks, with more processing power and a more attractive price point. Business applications like the management of the truck fleet started to flourish.Machine To Machine (M2M) became possible after a squeeze in cost and size. With this creation, if it was running out of fizzy cans, your neighborhood soft drink vending machine might complain.
Lastly, we reach the IoT era after a long journey of size and cost reduction, with a corresponding increase in computational power and the amount of data sensors that could be moved to a cloud or backend. Small, cheap, robust, and all over the place. Okay, that kind of thing. While IoT devices have actually become more compact and available, on the path to a connected and connected world there are still difficulties.
