The History and Evolution of IoT Technology

The Internet of Things (IoT) refers to a network of physical devices embedded with sensors, software, and connectivity that allow them to exchange data over the internet. Over the years, IoT has evolved from a futuristic concept to an everyday reality powering smart homes, connected cars, industrial automation, and wearable devices.

In this article, we’ll explore the timeline, key milestones, technological shifts, and future trends in IoT’s fascinating journey.

Early Concepts: Before “IoT” Had a Name

• 1960s – 1970s: Mainframe computers connected via ARPANET laid the groundwork for machine-to-machine (M2M) communication.
• 1982: The first internet-connected appliance—a Coca-Cola vending machine at Carnegie Mellon University—could report its inventory and temperature remotely.
• 1990: John Romkey connected a toaster to the internet at INTEROP conference.
