With 19,500 visitors, the number of visitors increased by 40 percent over the previous year.

Circa 150 exhibitors, both businesses and non-profit groups were represented. Apple showed [[Mac OS X]] running [[Open-source software|Open Source Software]]. Other highlights included the release of [[OpenGroupware.org]], [[OpenOffice.org]], a conversion to run Linux of several dozen [[Xbox|Xboxes]], some by a hardware modification by two solder points, some by utilizing so-called MechInstallers.

There was also a Programming Competition and on Sunday, 13 July 2003 from 13 to 14 o'clock a world record attempt took place: On a server 100 Linux desktop sessions with [[Gnome]] and [[K Desktop Environment|KDE]] were simultaneously running, which could be used by everyone on the Internet.

Besides the exhibition also sub-conferences were held at which renowned experts discussed a subject. There was, for example, a [[Debian]] conference and on Sunday there was a lecture on [[Trusted Computing Platform Alliance|TCPA]], followed by a discussion. The Business and Government sub-conference with 400 participants grew by about 60% compared to 2002. The free lecture program was opened on Friday by the Parliamentary State Secretary, [[Ministry of Economics (Germany)|Federal Ministry of Economics and Labour]], Rezzo Schlauch.

==== LinuxTag 2005 ====
LinuxTag 2005<ref>Website of LinuxTag 2005 https://www.linuxtag.org/2005/308.0.en.html</ref> took place from 22 to 25 June at the Messe Karlsruhe. It was the 11th LinuxTag and titled "Linux everywhere". As usual a conference with far more than 100 talks and presentations was accompanied by a large exhibition with booths from more than 160 companies and projects, plus on 22 June 2005 the business and administration sub-conference. Additionally workshops and tutorials were offered.

Keynote speaker [[Jimmy Wales]] announced a collaboration between Wikipedia and [[K Desktop Environment|KDE]] in his opening speech. Through a [[web API]] every program can directly access Wikipedia, which was used by the KDE Media Player [[Amarok (software)|Amarok]] version 1.3 to access the Wikipedia articles of artists.

The organizers counted about 12,000 visitors, a little less than in previous years, which was mainly caused by the newly introduced mandatory entrance fee and the hottest week of the year 2005.
