Bitnet Relay - Wikipedia, the free encyclopedia - Profile. BITNET Relay, also known as the Inter Chat Relay Network, was a chat network setup over BITNET nodes.
It predates Internet Relay Chat and other online chat systems. The program that made the network possible was called "Relay" and was developed by Jeff Kell of the University of Tennessee at Chattanooga in 1985 using the REXX programming language. The Relay servers were connected so that messages would travel hop-by-hop along the network of servers until they reached their destination.

Internet Relay Chat (IRC) is an application layer protocol that facilitates transfer of messages in the form of text.
The chat process works on a client/server model of networking. IRC clients are computer programs that a user can install on their system. These clients are able to communicate with chat servers to transfer messages to other clients. 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 transfer, including file sharing. Client software is available for every major operating system that supports Internet access. As of April 2011, the top 100 IRC networks served more than half a million users at a time, with hundreds of thousands of channels operating on a total of roughly 1,500 servers out of roughly 3,200 servers worldwide.
