Pop art was introduced to the art world at the International Exhibiton of the New Realists which featured American artists such as Roy Lichtenstein, Andy Warhol and European artists such as Yves Klein and Jean Tinguely. This exhibit hosted by the Sidney Janis Gallery demonstrated a connection between the European Nouveaux Realists and American Pop Art which upset many Abstract Impressionists. Mark Rothko, Philip Guston, and other artists quit the Sidney Janis Gallery in protest of this exhibition. They believed that the art world was becoming a form of mass commercialization and has lost all sense of romanticism, concept or meaning.
When it comes to shocking art, every artist knows the exhibit called When Attitudes Become Form in 1969 at the Kunsthalle Bern. The independent curator, Harald Szeemann, is responsible for changing the world of time-based media, performance art and the conversation surrounding what qualifies as art for years to come. He featured artists like Joseph Beuys, Eva Hesse and Bruce Nauman who worked in the movement of Arte Provera which provoked concepts, processes, information and situations through performance and conceptual art. It was an extensive exhibition including texts and amalgams of Pop, a Minimal and Conceptual art which became the greatest influence on experimentation within visual arts.
The International Surrealist Exhibiition was the first of its kind in the UK and created a big buzz around surrealism by exhibiting arts by artists such as Salvador Dali and Max Ernst. The 1936 exhibition was an outstanding success and the shows organizers educated the patrons of the exhibition with lectures and information sessions about surrealist art. It started the trend behind educating the public about the art as there was a massive positive response. There was also a large acceptance of the new surrealistic point of view and a rejection of realism making it an exhibition at the cornerstone of modern art.
