What is IRC?

IRC stands for “Internet Relay Chat”. It was originally written by Jarkko Oikarinen in 1988. Since starting in Finland, it has been used in over 60 countries around the world. IRC is a multi-user chat system, where people meet on “channels” (rooms, virtual places, usually with a certain topic of conversation) to talk in groups, or privately. There is no restriction to the number of people that can participate in a given discussion, or the number of channels that can be formed on IRC.


Internet Relay Chat (IRC) is a form of real-time Internet text messaging (chat) or synchronous conferencing. It is mainly designed for group communication in discussion forums, called channels, but also allows one-to-one communication via private message as well as chat and data transfers via Direct Client-to-Client.

As of May 2009, the top 100 IRC networks served more than half a million users at a time, with hundreds of thousands of channels (the vast majority of which stand mostly vacant), operating on a total of roughly 1,500 servers world-wide.
