Content generally refers to the subject matter, meaning or significance of a work of art, as opposed to its form. In modern art the dramatic succession of innovations in form from Impressionism onwards have meant that discussion of this has often taken precedence over that of content. In the 1960s and early 1970s the particularly radical flight from traditional forms of art that resulted in what became known as Conceptual art, gave rise to work in which form and content were fused in a new way.
