LinuxTag (German for "Linux-day") is a Free Software expo with an emphasis on Linux (but also BSD), held every summer in Germany. It is relatively large, claiming that it is the largest expo of this kind in Europe, drawing visitors from many countries.
The LinuxTag slogan is "Where .COM meets .ORG", as it includes both representatives from commercial companies and from nonprofit/community projects. The latter are given booths, free of charge, in the .org section, as long as there is room.
LinuxTag has also been a sponsor of several other projects, notably of Knoppix, a Linux Live CD. Knoppix is often used to showcase software running on Linux on a computer configured with a different operating system (usually Microsoft Windows or Mac OS X).
LinuxTag is sponsored by various IT-related companies and, at least in some of its iterations, by the German government.
LinuxTag 2007 faced calls for a boycott because it was officially held under the patronage of the German Interior Minister Wolfgang Schäuble, a member of the conservative CDU party.[1]
The first LinuxTag took place at the University of Kaiserslautern in 1996. The event was held there every year until 2000, when it was moved to Stuttgart for two years. From 2002-2005 it was held in Karlsruhe, and 2006 in Wiesbaden. Since 2007, LinuxTag has taken place in Berlin; in 2011 it will be held from 11 to 14 May.
