How often do you catch yourself commanding, "Alexa, turn on the music," or “Hey Google, show me the front door camera”? Quite a lot of time.
So, let me be the one to break it to you that you wouldn’t be making these commands if it weren’t for IoT—which means Internet of Things. So, tell me, do you know where this technology originated and how it worked at first and then evolved into one of our most desirable pieces of comfort?
Let’s learn everything from the beginning to how IoT turned into a game-changer.
Now, with the help of these changes, the idea of devices communicating with one another went from being a probable theory to a possible phenomenon because, for the very first time now, everyday objects could collect information, process it, and send it across a network.
This change moved IoT out of research labs and into real products:
This decade is considered IoT’s turning point—the moment it left the stage of “future possibility” and became part of daily life. It set up the foundation for the smarter environments we see today, including intelligent homes, connected vehicles, and early versions of smart cities.
The systems operate through network connections to perform various tasks independently.
Inside the home, IoT appliances brought automated functionality to residential spaces:

Let’s learn everything from the beginning to how IoT turned into a game-changer.
Early History of IoT and the First Connected Devices
The Idea Begins (1980s–1990s)
- IoT's history can be traced back to the 1980s and 1990s, when the technology was in the making.
- With the enhancement of computer networks and processing power, a few scientific minds started to ponder whether or not machines can actually converse with one another without human assistance.
The Term “Internet of Things” Is Born (1999)
- The year 1999 was marked by the introduction of the term Internet of Things by the British tech genius, Kevin Ashton.
- He demonstrated the potential of RFID (Radio Frequency Identification) technology to the extent that it could enable computers to recognize and monitor physical items without any manual intervention.
- This made it possible for machines to “detect” the physical environment around them, and then relay the info through the network, which was an essential factor in the evolution of present-day IoT technology.
The First Real IoT Experiment
- One of the earliest working IoT devices was a Coca-Cola vending machine at Carnegie Mellon University.
- The machine was connected to the internet and could report:
- Whether drinks were stocked
- Whether the drinks were cold
- Whether the drinks were cold
- It may sound simple today, but it proved that a device could send real-time information without human input.
Why It Mattered
- These early ideas and experiments moved IoT from theory to reality.
- For the first time, everyday objects could:
- Collect data.
- Communicate over a network.
- Operate without direct human involvement.
- Communicate over a network.
- Operate without direct human involvement.
- This became the foundation of today’s interconnected world—from smart homes to industrial automation.
Growth of IoT in the 2000s: From Idea to Real-World Technology
Before the 2000s we had IoT, but on paper only, so the 2000s were the years when IoT was brought to practical use. The speed of the internet quickened; Wi-Fi became a dime a dozen, Bluetooth got better, and even low-cost sensors were created.Now, with the help of these changes, the idea of devices communicating with one another went from being a probable theory to a possible phenomenon because, for the very first time now, everyday objects could collect information, process it, and send it across a network.
This change moved IoT out of research labs and into real products:
- Smart Home Devices: Devices like thermostats, security systems, lighting controls, and appliances, began entering consumer markets.
- Wearable Technology: The initial fitness trackers and smartwatches showed us how IoT could monitor health and movement.
- Industrial IoT: It started taking shape as companies used connected systems to:
- Monitor equipment performance.
- Detect faults early.
- Track assets across factories and warehouses.
- Improve production accuracy and reduce manual effort.
- Detect faults early.
- Track assets across factories and warehouses.
- Improve production accuracy and reduce manual effort.
This decade is considered IoT’s turning point—the moment it left the stage of “future possibility” and became part of daily life. It set up the foundation for the smarter environments we see today, including intelligent homes, connected vehicles, and early versions of smart cities.
IoT Innovation in Daily Life and Smart Homes
As you can see, a myriad of tech companies has started to come up with many fascinating IoT solutions, which have indeed become a crucial part of our daily life. The home features voice assistants Alexa, Siri, and Google Assistant, which enable users to operate lights and appliances and play music and set alarms through voice commands.The systems operate through network connections to perform various tasks independently.
Inside the home, IoT appliances brought automated functionality to residential spaces:
- Refrigerators keep track of items stored in them and send an alert if groceries finish.
- Smartphones can control ovens and washing machines.
- Smart thermostats can make adjustments to temperature depending upon time, weather, and user behavior.
IoT Integration Across Industries
| Industry | How IoT Works | Benefits |
| Manufacturing & Supply Chain | There are IoT sensors which: monitor machinery, keep track of inventory, detect temperature, and control production lines automatically. | Predict if any equipment is not working, decreases downtime, lowers repair costs, avoids any delay in shipping, and improves efficiency. |
| Agriculture | Soil moisture, health of crops, level of fertilizers, and changes in weather are predicted and monitored through sensors. | Water and resources are saved, quality of crops is increased, and manual workload is also reduced for farmers. |
| Healthcare | Devices that can be worn monitor heart rate, glucose, and sleep. If anything goes wrong, an immediate alert is sent. | Faster diagnosis, improved patient safety, reduced emergency response time, and better remote care. |
| Retail & Commercial | Automated checkout systems, digital pricing shelves, IoT security cameras, and sensors that track shopping patterns and shelf stock levels. | Faster shopping reduced manual work, fewer stock outs, and better understanding of customer behavior. |
Advantages of IoT Technology in a Connected World
Convenience in Daily Life
The Internet of Things enables people to perform their daily responsibilities through automated systems. The smartwatch enable users to monitor their heart rate and blood pressure and track their step count. The room temperature system operates independently to adjust the environment while the smartwatch tracks your vital signs.Efficiency and Automation in Business
The implementation of IoT technology enables businesses to execute tasks, which would otherwise require extensive manual work. The current implementation of sensors enables organizations to detect system problems and track inventory levels and generate faster results.Improved Safety and Risk Prevention
The Internet of Things enables sensors to identify dangerous situations including factory gas leaks and smoke detection and machine irregularities and environmental threats. Smart alarms in residential settings monitor both carbon monoxide levels and fire safety and electrical system performance.
