Raoul Hausmann was the leader of the Berlin Dada movement in 1917, and the creator of photomontage. Photomontage is the art of arranging and glueing photographs or other found illustrative material onto a surface. Strictly speaking it is a type of collage, which was not new to Dada artists; however it was previously used in a refined manner, particularly by the cubists, who had transformed the found materials taken from poplar cultre into bautiful art.  With Huasmann, howeer, collage retained the look and feeling of popular culture, especially the advertising look seen in the mass media.

Collage was widely used in the 20th century and quickly began to introcude three-dimensional elements, most of which are "found" materials.  Joan Miro, who is frequently associated with the Dada movement produced several series of collage works between 1929 and 1940.

Richard Hamilton was one of the founders of the British pop movement in 1955. Pop art embraced everyday art from ads, commercials, the media and culture at large, particularly advertising. In 1957, Hamilton wrote what pop art was for him: "Popular (designed for a mass audience); transient (short-term); expendable; low cost; mass produced; young (aimed at youth); witty; sexy; gimmicky; glamorous; and last but not least, Big Business."
