According to Wikipedia, the initial release of Debian happened 16 August 1993. In other words, it's Debian's birthday and you're all invited. 'During the Debian Birthday, the Debian conference will open its doors to anyone interested in finding out more about Debian and Free Software, inviting enthusiasts, users, and developers to a half day of talks relating to Free Software, the Debian Project, and the Debian operating system.' Over the years, Debian has been forked a number of times. Some of the more well-known forks are Ubuntu and Knoppix. The latest release of Debian pure blend was Debian 7.1 'Wheezy' on June 15th 2013."
