Today, there are tens of thousands of separate newsgroups discussing everything from popular computers to popular culture, from business to recreation, and from the serious to the absurd. Newsgroup A newsgroup is an electronic bulletin board where users can post and read messages about the subject being discussed. Newsgroups Newsgroups are divided into different categories according to the subject matter involved. The category type is the first part of a newsgroup's name. For instance, if a newsgroup's name is comp.ibm, the first part of the name, comp, tells you that the newsgroup is about computers.
Postings can contain anything from a discussion of business to advertisements.
These newsgroups are reserved for discussions about computers. They include postings of announcements or administrative concerns. This is where you will find discussions of travel, movies, books, television, music, and sports. The alternative newsgroups are the most controversial of all. With the other newsgroup categories, a new group must be approved by Usenet.
