Today, Usenet has diminished in importance with respect to Internet forums, blogs and mailing lists.
In most newsgroups, the majority of the articles are responses to some other article.
The set of articles that can be traced to one single non-reply article is called a thread.
The blue, green, and red dots on the servers represent the groups they carry.
Arrows between servers indicate newsgroup group exchanges (feeds).
The format and transmission of Usenet articles is similar to that of Internet e-mail messages.
