Conceptual art emerged in the 1960s in a drastic move from conventional art styles. Art concerned itself more with ideology rather than aesthetic or craftsmanship. This movement fought against the school of thought which said art had to be in some tangible form by concentrating its attention on the idea as the most important aspect of art. Artists wanted their audiences to think actively and often used performances, words, and unusual materials to express themselves. Remarkable for its height of popularity in the late 1960s and 1970s, Conceptual Art focused on questioning art itself while melting the barriers set between art and daily objects or deeds. This movement was helped by many artists like Sol LeWitt, Joseph Kosuth, and Yoko Ono. Diversity of approaches within the scope of Conceptual Art appeared in the geometric structures of LeWitt, language and philosophy of Kosuth, and socially active as well as participatory artworks of Ono. Conceptual art redefined the interactions of the viewer, the artist, and the art piece by highlighting ideas and concepts. This movements still affects contemporary art practices by stressing the need for active participation, critque, and dematerialization of the art object. Conceptual art moves beyond physical forms and portrays challenges to conventional forms of expressions of art by opening up new vistas of creativity of artistic expressions.
