With the arrival of Usenet, developers could collaborate on a worldwide level like never before and it made it easy to share software. Usenet (built on top of the infrastructure that is now called the Internet) was in many ways a precursor to today’s Internet forums and predated the World Wide Web by over a decade. Usenet is a worldwide distributed discussion system. It was developed from the general-purpose UUCP dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea. Users read and post messages to one or more categories, known as newsgroups.
