The term "Internet of Things" was first coined by Kevin Ashton in 1999 while working on supply chain optimization at Procter & Gamble. However, the idea behind connected devices predates this term.
Detailed Explanation
In 1999, Kevin Ashton created the term 'Internet of Things' to describe a network of interconnected devices that could communicate and share information. This concept, while popularized in the late 90s, actually has its roots in earlier ideas of connected devices that date back much earlier than Ashtonβs work.
Examples & Analogies
Think of the term 'Internet of Things' like a nickname for a group of advanced gadgets. Just as a person might have a nickname that captures their essence, the term captures the essence of smart devices that work together. Before the nickname became popular, these gadgets were already interacting in simpler forms.
