The flag day in 1986 on which all of the non-local groups on the Usenet had their names changed from the net.- format to the current multiple-hierarchies scheme. Used especially in discussing the history of newsgroup names. "The oldest sources group is comp.sources.misc; before the Great Renaming, it was net.sources."
