Jarkko Oikarinen, known on IRC as 
WiZ was the developer of the first Internet chat network, called 
IRC, short for 
Internet Relay Chat. He wrote the first 
server and 
client in August 1988. It was first written to replace a program called MUT (MultiUser Talk) on a 
BBS called OuluBox in Finland. Jarkko Oikarinen found inspiration in Bitnet Relay Chat which operated on the 
Bitnet network.
