immersive or sensor-based environments, and investigating the artistic potential of electromagnetic fields – are considered across genres and media, examined in terms of their artistic applicability, and realized in productions. The name Hertz Lab obviously refers to the German physicist Heinrich Hertz. Archives and collections The ZKM Collection was founded by the ZKM's first director, Heinrich Klotz, in the early 1990s and has been added to ever since. The collection is based on a specific approach to the different art genres and media: whereas painting and sculpture were hermetically sealed off from the new influences of video art and photography which were gradually establishing themselves, the ZKM's collecting activity is distinguished by transcending such traditional genre divisions. While the Museum of Contemporary Art's collection contained artworks of all genres from the very beginning, the Media Museum's collection initially only contained works of interactive media art most of which were produced in-house. Over 500 international guest artists produced a vast number of works at the ZKM, which entered the ZKM Collection after their initial presentation in Karlsruhe. Consequently, the ZKM has one of the largest collections of media art in the world, extending back to the beginning of video art, electronic installations, and holography. In addition to these there is the collection of approximately 1,200 art videos and 13,800 audio tracks, which are not stored in the museum, but can be accessed via the ZKM | Media Library. The Video Collection was one of the first of its kind in Germany, and helped to raise public awareness of video as an independent art form. The collection contains works of video art from the 1960s, 1970s, and 1980s, and other works, such as the video magazine Infermental. Through the work of the Laboratory for Antiquated Video Systems, which is connected to the Media Library, it has been possible to rescue extensive video collections in Europe and the USA from degenerating, and make them accessible to the public. The Audio Collection contains contemporary music with an emphasis on electroacoustic music. In addition to audio recordings, the collection includes scores, specialist publications, historic photographs, and posters. Of especial importance is the International Digital Electro-acoustic Music Archive (IDEAMA), which includes pieces of electro-acoustic music from its beginnings through to the present. In addition to works of video art and electronic music, the ZKM acquires archives and documents on the electronic arts, that is, on video
