The History of IoT: Evolution of Connected Technology

The History of IoT traces back to the early 1980s when connected devices first emerged. Over decades, IoT evolved, revolutionizing industries through smart automation, real-time data, and AI integration. Today, it powers smart homes, healthcare, and industries worldwide.

1. History of IoT Technology: Key Milestones
& Growth

Introduction

The history of IoT technology dates back several decades, even before the term Internet of Things
(IoT) was coined. From early RFID applications to today’s interconnected smart devices, IoT has
revolutionized industries worldwide. This article explores the key milestones in IoT's evolution and its
continuous growth.



Early Beginnings of IoT Technology

The concept of IoT started with machine-to-machine (M2M) communication. In the 1980s and
1990s, researchers explored ways to connect devices via networks. The first notable IoT application
was in 1982 when Carnegie Mellon University developed an internet-connected Coca-Cola vending
machine that could report inventory and temperature.

Another key development was the invention of RFID (Radio Frequency Identification) technology in
the 1990s. RFID allowed objects to communicate wirelessly, laying the foundation for IoT sensor
technology.

2. The Birth of the Term "Internet of Things"

In 1999, Kevin Ashton, a British technology pioneer, coined the term "Internet of Things" while
working at Procter & Gamble. He envisioned a world where devices could collect and share data
automatically. This idea gained traction as the internet became more widespread and sensor
technology advanced.
