Contemporary art is notoriously hard to define. The most widely accepted definition of contemporary art is that it refers to artworks created between 1945 and the present day. Contemporary artworks are therefore defined simply by time period, regardless of the style, medium (sculpture,
painting, photography, drawing, or printing), or artistic movement they belong to. Contemporary art follows from modern art, which is broad term used to define art produced between the 1850s and 1945.
However, some art historians set the start date of contemporary art in the 1960s with the emergence of pop art, an artistic movement that represented a radical break from modernism.
Finally, a third definition of contemporary art is that it must be an artwork which either relates to practices and aesthetic designs that convey ideas or concepts (such as conceptual art), transcends boundaries between art and what traditionally is not considered art (for instance performance art), or that goes beyond the borders of art as they are understood by modern and classical art.
As we can see, there isn't a clear definition of contemporary art, but rather several definitions of contemporary art that ultimately all complement each other. Indeed, art today has become so diverse, in terms of the mediums, techniques and styles as well as artistic themes or subject matter that it has become impossible to pinpoint one definition.
