Beginning with work in the tradition of visual poetry, Weibel produced «media-based literature» in the form of paper, photographic and object poems, body texts and material poetry, text objects and video texts. Conceptual works and actions followed, together with media analyses employing the media under scrutiny, initial TV experiments on Austria's ORF, and later numerous installations deploying film and video. The publication of candid sexual representations in a black book on Viennese Actionism led to a lawsuit against its publishers Valie Export and Peter Weibel in 1970. Both artists continued to support each other's projects into the late 1970s, with Weibel writing the screenplays for Export's films «Unsichtbare Gegner» («Invisible Opponents»), 1977, and «Menschenfrauen» («Humanwomen»), 1979. His subjects are less body-oriented, however, and deliver from a media-specific and semiological viewpoint socially critical analyses of systems and machines like film, television, and the visual arts. Weibel was an early and eloquent champion of a theory of media and communication, which he repeatedly applied in investigating the inherent laws and mechanisms of the various media.
