Created in 1988 by Jarkko Oikarinen in Finland, IRC was designed to enable real-time, text-based communication over the internet. Inspired by the multi-user talk programs on UNIX systems, Oikarinen wanted a system that was more flexible and scalable.
IRC quickly became the backbone of online communities in the 90s and early 2000s, hosting discussions ranging from programming and hacking to gaming and general socializing. Unlike modern chat services, IRC was entirely decentralized—anyone could set up a server, create channels, and communicate without corporate control.
Though its popularity has declined with the rise of modern platforms, IRC still thrives among enthusiasts, open-source communities, and privacy advocates who prefer its lightweight, no-nonsense approach to online chat.
