LinuxTag (German literally: "LinuxAssembly", figuratively: Linux congress or meeting) is a Free Software exposition with emphasis on Linux (but also BSD), held annually in Germany. Its organisers claim it to be the largest computer exposition in Europe, drawing visitors from many countries, lasting for several days.
The LinuxTag slogan is "Where .COM meets .ORG", as it includes both representatives from commercial companies and from nonprofit/community projects. The latter may use exposition space free of charge in the .org section.
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.
In the 2007, the LinuxTag faced calls for a boycott because, as it was officially held under the patronage of the German Interior Minister Wolfgang Schäuble, a member of the conservative CDU party.
