The concept of embedded systems—small computers integrated into physical devices—began in the 1970s. These systems were designed to perform specific tasks, such as controlling machinery in factories or managing temperature in household appliances.

In the early 1990s, the development of smart devices that could communicate over a network started to emerge. The introduction of the internet in the 1980s and 1990s created an ideal environment for the growth of networked devices. One of the earliest examples of this was the Internet-connected Coca-Cola vending machine at Carnegie Mellon University in 1982. The machine was equipped with sensors to detect whether the drinks were cold and available, and it communicated this data over the internet. This simple concept laid the groundwork for future IoT innovations.

2. The Coining of the Term IoT (1999)

The term "Internet of Things" was coined in 1999 by Kevin Ashton, a British technology pioneer, who was working at Procter & Gamble. Ashton used the term to describe a network of devices that could automatically collect and share data using sensors. The idea was revolutionary: instead of requiring human intervention to gather information, devices would autonomously collect data and make decisions based on real-time information.

At the time, the internet was still in its infancy, and the idea of connecting everyday objects seemed far-fetched. However, Ashton’s vision of a connected world would go on to influence the development of IoT over the next few decades.

Key Milestones in the Growth of IoT
