Most of us can remember life before “smart” devices; smart speakers, smart thermostats, smart homes and the like. It wasn’t that long ago that our devices were like a bunch of loners at a party – they didn't talk to each other.
Your thermostat didn't know your temperature preferences depending on the time of day and your watch couldn’t tell you how many miles you ran.
Which makes the fact that most of us also now rely on several IoT devices throughout our lives daily, pretty fascinating and, in the history of technology, a pretty rapid mass adoption.
The Internet of Things (IoT) has transformed the way we interact with technology and the world around us. It has completely changed how we interact with everyday objects and appliances and revolutionized industries, from healthcare to manufacturing.
So, how did we get to this point of interconnected magic? Get ready for a wild ride!
The concept of connecting devices and machines to the internet predates the term "IoT." In the mid 20th century, researchers and innovators began exploring ways to link physical objects to the digital world through radio-frequency identification (RFID).
One early and notable example of RFID technology being used for IoT-like purposes was during World War II.
In the 1940s, the British Royal Air Force used an early form of RFID technology to distinguish between friendly and enemy aircraft. They developed a system known as "Identification Friend or Foe" (IFF), which used radio waves and transponders to help radar operators identify aircraft.
Decades later, in the early 1990s, is when we first hear the term "Internet of Things," coined by British technology pioneer Kevin Ashton, who envisioned a world where everyday objects could communicate with each other and with us.
In all reality, IoT as we know it really only kicked off 20 years ago in the early 2000s marking a significant turning point in IoT software development.

The OnStar system in the early 2000s exemplified the use of wireless connectivity in IoT devices, particularly in the automotive sector. It demonstrated the potential of connected vehicles for improving safety, security, and convenience through the use of wireless networks and remote communication with service centers.
As we entered the mid-2010s, IoT software development gained momentum and what we think of now as well-known brands relied heavily on these technology advancements.
The integration of IoT with cloud computing platforms allowed for scalable, real-time data processing and storage. This shift reduced the computational burden on IoT devices.
Amazon Web Services (AWS) IoT played a significant role in leveraging cloud computing technologies during the 2010s to advance the Internet of Things (IoT) ecosystem.
Their use of cloud computing empowered organizations to build, scale, and secure IoT solutions efficiently. It streamlined device management, data processing, and analytics, and enabled the development of innovative IoT applications across various domains.
Standardization efforts led to the development of IoT-specific communication protocols like MQTT and CoAP, enhancing interoperability between devices and applications.
One prime example of an IoT product in the 2010s that heavily relied on standard protocols is the Philips Hue smart lighting system.
By relying on established and widely accepted communication standards, Philips Hue was able to offer interoperability with a range of other smart home devices, voice assistants, and IoT platforms.
This not only made it more user-friendly but also encouraged the development of a vibrant ecosystem of third-party applications and integrations, enhancing its capabilities and utility in the IoT landscape of the 2010s.
As IoT products were really taking off around this time, increased awareness of IoT security vulnerabilities prompted developers to prioritize security measures, such as encryption and authentication, to protect data and devices.
One prominent example of an IoT product that placed a strong emphasis on security in the 2010s was the August Smart Lock.
The August Smart Lock is a connected smart lock designed to enhance the security of residential homes while providing convenient remote access.
The August Smart Lock used secure authentication, data encryption, access control, a secure mobile app, physical security features (being a lock and all), security auditing , firmware updates and secure remote access.
The August Smart Lock served as a model for how IoT products in the 2010s could prioritize security to gain the trust of consumers and improve overall safety and convenience.
IoT generated vast amounts of data and developers quickly started seeing the opportunity of leveraging big data analytics and machine learning to derive actionable insights from this data, paving the way for predictive maintenance and improved decision-making.
One notable example of an IoT product that heavily relied on data analytics in the 2010s is the Fitbit wearable fitness tracker and associated platform. Fitbit's devices and ecosystem were built on the extensive collection and analysis of health and fitness data.
Fitbit's success in the 2010s was built on its ability to collect, analyze, and visualize health and fitness data, empowering users to make informed decisions about their well-being and helping healthcare professionals and researchers gain insights into health trends and outcomes. It was a prime example of how IoT devices could harness data analytics to drive personal health and wellness.
