A connected future...

https://en.wikipedia.org/wiki/Internet_of_Things

The Internet of Things (IoT) is the network of physical objects—devices, vehicles, buildings and other items—embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data.[1] The IoT allows objects to be sensed and controlled remotely across existing network infrastructure,[2] creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit;[3][4][5][6][7][8] when IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, smart homes, intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Experts estimate that the IoT will consist of almost 50 billion objects by 2020...

The Internet of Things: How the Next Evolution of the Internet Is Changing Everything

It is important to agree on a definition. According to the Cisco Internet Business Solutions Group, IoT is simply the point in time when more “things or objects” were connected to the Internet than people.

In 2003, there were approximately 6.3 billion people living on the planet and 500 million devices connected to the Internet.

By dividing the number of connected devices by the world population, we find that there was less than one (0.08) device for every person.

Based on Cisco's definition, IoT didn’t yet exist in 2003 because the number of connected things was relatively small given that ubiquitous devices such as smartphones were just being introduced. For example, Steve Jobs, Apple’s CEO, didn’t unveil the iPhone until January 9, 2007 at the Macworld conference.

Explosive growth of smartphones and tablet PCs brought the number of devices connected to the Internet to 12.5 billion in 2010, while the world’s human population increased to 6.8 billion, making the number of connected devices per person more than 1 (1.84 to be exact) for the first time in history.

Refining these numbers further, Cisco estimates the IoT was “born” sometime between 2008 and 2009 (see Figure 1).
