What Does mIRC Mean?
mIRC is one of the earliest and most iconic Internet Relay Chat messaging services. It was created in 1995 and distributed as a shareware program. It reached its peak use around 2003-2005, long before the full advent of modern social media. Still functional even in modern times, mIRC is compatible with the Windows operating system architecture. In fact, its scripting language is ever-evolving and has never stopped being updated.
