The original seven hierarchies were
comp.*, misc.*, news.*, rec.*,
sci.*, soc.*, and talk.*. They were open and free for anyone to participate with (except for the
moderated newsgroups), though they were subject to a few general rules governing their naming and distribution.
alt.* is not part of the original seven but was created separately as a venue with more freedom and fewer rules than the Big 7. During April 1995, a time when Usenet traffic had increased significantly, humanities.* was introduced and it and the seven hierarchies created by the Renaming comprise the present so-called "Big 8". == Hierarchies ==
