20 Year Usenet Timeline
Google has a nice history view of the past 20 years of Usenet archives via Google Groups, giving it a total of more than 800 million messages starting 1981! Lots of great stuff in there like Time Berners-Lee’s announcement of what become the WWW or Linus Torvalds’ post about his “pet project” or Jeff Bezos’ hirering.
A good list can be found here: 20 Year Archive on Google Groups.
