    A large text presents the history of Computer Art. The history of the artistic uses of computers and computing processes is reconstructed from its beginnings in the fifties to its present state. It points out hypertextual, modular and generative modes to use computing processes in Computer Art and features examples of early developments in media like cybernetic sculptures, video tools, computer graphics and animation (including music videos and demos), video and computer games, pervasive games, reactive installations, virtual reality, evolutionary art and net art. The functions of relevant art works are explained more detailed than is usual in such histories. From October 2011 to December 2012 the chapters have been published successively in German (The English translation started in August 2013 and was completed in June 2014)

    The development of the use of computers and software in art from the Fifties to the present is explained. As general aspects of the history of computer art an interface model and three dominant modes to use computational processes (generative, modular, hypertextual) are presented. The "History of Computer Art" features examples of early developments in media like cybernetic sculptures, computer graphics and animation (including music videos and demos), video and computer games, reactive installations, virtual reality, evolutionary art and net art. The functions of relevant art works are explained more detailed than usual in such histories. The German version was completed in December 2012. The last chapter of the English translation was published in June 2014. First update: September 2015

    Die Entwicklung von Computer und Software von den fünfziger Jahren bis heute wird vorgestellt. Als Leitkriterien der Geschichte der Computerkunst werden ein Interface-Modell und drei Arten, Rechenprozesse einzusetzen (generativ, modular, hyptertextuell), vorgeschlagen. Die "Geschichte der Computerkunst"/"History of Computer Art" erörtert Beispiele aus frühen Entwicklungsphasen von Kunstformen wie Kybernetische Skulpturen, Computergraphik und -animation (einschließlich Musikvideos und Demos), Videokunst und Computerspielen, reaktive Installationen, Virtuelle Realität, Evolutionäre Kunst und Netzkunst. Die Funktionen der ausgewählten Werke werden detaillierter vorgestellt als dies in vergleichbaren Geschichten üblich ist. Die deutsche Version wurde bis Dezember 2012 kapitelweise in IASLonline Lektionen/Lessons in Net Art publiziert. Das letzte Kapitel der englischen Version wurde Juni 2014 veröffentlicht. Im September 2015 wurde ein erstes Update eingestellt
