What is the difference between Google Groups and Usenet?
Google archives most newsgroups on Usenet and makes the old articles available through a page-based interface. Most news servers only hold articles for a short time depending on how the news administrator has set up the system. Google also provides a method for creating new Google Groups that are Google-specific; such groups do not circulate on Usenet news servers. Google is not a traditional news service provider. Neither the newsgroup archives nor the non-Usenet Google Groups can be accessed by a news reader.
