Some very early users of the Internet, not the worldwide web as we know it today, but the Internet from the early 1980s, will have heard of, and likely used, Usenet.This was the collective name applied to text based electronic bulletin boards that were used to communicate in the days before the web and email existed, and that are still in use today.The Usenet posts were first collected and organized for worldwide web use in 1995, by a company called Deja News.In 2001, Google bought Deja News and applied their considerable search expertise to Usenet posts.The result is Google Groups.
