Newsgroups are another popular part of the Internet, allowing open forums for discussion and chat.
All of the newsgroups are part of a server called USENET, which is accessed through your ISP's Nes Server, and distributed to all other news servers. It's handled in a manner similar to that of E-Mail.
Most newsgroups have address that follow area.type.topic, like alt.tv.x-files or comp.lang.perl.
