Usenet

https://wikipedia.org/wiki/Alt.*_hierarchy
https://wikipedia.org/wiki/Great_Renaming

• comp.* – computer-related discussions (comp.software, comp.sys.amiga)

• humanities.* – fine arts, literature, and philosophy (humanities.classics, humanities.design.misc)

• misc.* – miscellaneous topics (misc.education, misc.forsale, misc.kids)

• news.* – discussions and announcements about news (meaning Usenet, not current events) (news.groups, news.admin)

• rec.* – recreation and entertainment (rec.music, rec.arts.movies)

• sci.* – science related discussions (sci.psychology, sci.research)

• soc.* – social discussions (soc.college.org, soc.culture.african)

• talk.* – talk about various controversial topics (talk.religion, talk.politics, talk.origins)

Groups in the alt.* hierarchy tend to be more specialized or specific.
Companies and projects admin their own hierarchies to discuss their products and offer community technical support, such as the historical gnu.* hierarchy.
Regional and language-specific hierarchies such as japan.*, malta.* and ne.* serve specific countries and regions.
Informal sub-hierarchy conventions also exist. *.answers are typically moderated cross-post groups for FAQs.
