Evolution of IoT (Internet of Things) The Internet of Things (IoT) has undergone significant evolution since its conceptual beginnings, shaped by technological advancements and changing societal needs. Below is a timeline of key stages and milestones in the development of IoT: 1. Pre-IoT Foundations (1960s–1990s) The groundwork for IoT was laid long before the term "IoT" existed. The development of the internet, microchips, and wireless communication technologies provided the foundational elements necessary for IoT. 1960s: Early stages of networking, with the creation of ARPANET, a precursor to the modern internet. 1970s: The introduction of microprocessors and the concept of embedded systems allowed the integration of computing power into physical devices. 1980s–1990s: Advancements in wireless communication (Wi-Fi, RFID) and the expansion of the internet
