History of Internet of Things?
The concept of the Internet of Things (IoT) dates back to the early 1980s, when a Coca-Cola vending machine at Carnegie Mellon University became the first Internet-connected device. However, the term “Internet of Things” was coined in 1999 by Kevin Ashton, a British technology pioneer, while working at Procter & Gamble.
The IoT gained momentum in the 2000s with the rise of RFID (radio frequency identification) and wireless sensor networks, which allowed devices to communicate and share data. In 2008, the number of connected devices surpassed the global human population, marking a turning point for the IoT.
With advancements in cloud computing, 5G, and artificial intelligence, IoT applications have expanded to industries such as healthcare, smart homes, industrial automation, and transportation. Today, IoT continues to revolutionize daily life, powering smart cities, self-driving cars, and wearable technology. As connectivity improves, IoT is expected to grow exponentially, shaping the future of technology and data-driven decision-making.
