Here is a little background information on the Usenet story;
The Usenet was brought to life at the University of North Carolina in 1979. Three IT-Students, Tom Truscott, Steve Bellovin and Jim Ellis connected two Unix-servers and thus created the Usenet as an alternative to the Arpanet, run by the US Army and scientific institutes. In the next 30 years Arpanet became the highly popular Internet and replaced Usenet as the dominant network. However, the Usenet still exists in its exact same shape and is now offering a unique powerful access to a huge archive of uncensored information and files.
