By 1930, Modernism had won a place in the establishment, including the political and artistic establishment, although by this time Modernism itself had changed.

One of the most visible changes of this period was the adoption of new technologies into daily life of ordinary people in Western Europe and North America. Electricity, the telephone, the radio, the automobile—and the need to work with them, repair them and live with them—created social change. The kind of disruptive moment that only a few knew in the 1880s became a common occurrence. For example, the speed of communication reserved for the stock brokers of 1890 became part of family life, at least in middle class North America. Associated with urbanization and changing social mores also came smaller families and changed relationships between parents and their children.

Since then, many artists have embraced minimal or postminimal styles, and the label "Postmodern" has been attached to them.

These performances were intended as works of a new art form combining sculpture, dance, and music or sound, often with audience participation. They were characterized by the reductive philosophies of minimalism and the spontaneous improvisation and expressivity of abstract expressionism. Images of Schneeman's performances of pieces meant to shock are occasionally used to illustrate these kinds of art, and she is often seen photographed while performing her piece Interior Scroll. However, according to modernist philosophy surrounding performance art, it is cross-purposes to publish images of her performing this piece, for performance artists reject publication entirely: the performance itself is the medium. Thus, other media cannot illustrate performance art; performance is momentary, evanescent, and personal, not for capturing; representations of performance art in other media, whether by image, video, narrative or otherwise, select certain points of view in space or time or otherwise involve the inherent limitations of each medium. The artists deny that recordings illustrate the medium of performance as art.
